Graph this line y+4=1/4(x+10)
Answer:
See below
Step-by-step explanation:
I would start off writing the equation in the slope intercept form of a line
y + 4 = 1/4(x + 10) Distribute the 1/4
y + 4 = 1/4x + 10/4 Simplify 10/4
y + 4 = 1/4 x + 5/2 Subtract 4 from both sides
y = 1/4 x + 5/2 -4
y = 1/4 x + 5/2 - 8/2
y = 1/4 x - 3/2
Then I used the free graphing calculator Desmos to graph.
FIND THE TWO POINTS HAVING AN X-COORDNATE OF 3 WHOSE DISTANCE FROM THE POINT(-2,-1) IS 13.
POINT 1: (3, ?)
POINT 2: (3, ?)
To find the two points having an x-coordinate of 3 whose distance from the point (-2, -1) is 13, you can use the distance formula:
Distance = √((x2 - x1)^2 + (y2 - y1)^2)
where (x1, y1) is the coordinates of the first point, and (x2, y2) is the coordinates of the second point.
In this case, you can use the distance formula to find the y-coordinates of the two points having an x-coordinate of 3:
Distance = √((3 - (-2))^2 + (y - (-1))^2)
= √(5^2 + (y + 1)^2)
= √(25 + y^2 + 2y + 1)
= √(26 + y^2 + 2y)
= 13
If you set the distance equal to 13 and simplify the equation, you get:
y^2 + 2y + 12 = 0
This is a quadratic equation, which means it can be solved using the quadratic formula:
y = (-b ± √(b^2 - 4ac)) / (2a)
where a, b, and c are the coefficients of the quadratic equation.
Substituting the values into the quadratic formula, you get:
y = (-2 ± √(-2^2 - 4 * 1 * 12)) / (2 * 1)
= (-2 ± √(-4 - 48)) / 2
= (-2 ± √(-52)) / 2
Since the square root of a negative number is not a real number.

Samuel went to the grocery store and purchased cans of soup and frozen dinners. Each can of soup has 300 mg of sodium and each frozen dinner has 450 mg of sodium. Samuel purchased 5 more frozen dinners than cans of soup and they all collectively contain 6000 mg of sodium. Write a system of equations that could be used to determine the number of cans of soup purchased and the number of frozen dinners purchased. Define the variables that you use to write the system.
ax + by = 6000 and a + 5 = b are two equations that might be used to calculate how many soup cans and frozen dinners were purchased.
What is an equation?
There are several methods to define a formula. A mathematical statement that establishes the equivalence of two mathematical expressions is the definition of an equation in algebra.
This is best shown by the formula 3x + 5 = 14. In this instance, the word equal comes between the phrases 3x + 5 and 14. Even the most basic algebraic equations include the usage of mathematical variables.
Let frozen supper be y and soup cans be x.
X now has 300 mg of sodium in it.
x = 300
Y also has 450 mg of sodium in it.
y = 450
Samuel reportedly buys five more frozen dinners than soup cans, and they all have a combined salt content of 6000 mg.
Let the number of frozen dinners be "b," and the number of soup cans be "a."
ax + by = 6000
⇒ a(300) + b(450) = 6000 ...1
Samuel bought 5 more frozen dinners than soup cans, according to the inquiry, which results in equation
a + 5 = b ...2
Now, by changing the value of b in equation 1 we obtain,
⇒ a(300) + (a + 5)(450) = 6000
⇒ 300a + 450a = 6000 - 2250
⇒ 750a = 3750
⇒ a = 3750/750
⇒ a = 5
By changing the value of an in equation 2, we obtain
⇒ 5 + 5 = b
⇒ b = 10
So, ax + by = 6000 and a + 5 = b are two equations that might be used to calculate how many soup cans and frozen dinners were purchased, respectively, where x and y stand for soup cans and frozen dinners, respectively, and a and b stand for the quantity of soup cans and frozen dinners.

Suppose the average yearly salary of an individual whose final degree is a master's is $49 thousand less than twice that of an individual whose final degree is a
bachelor's. Combined, two people with each of these educational attainments earn $116 thousand. Find the average yearly salary of an individual with each of
these final degrees.
Answer:
Bachelor's Degree: $55,000
Master's Degree: $61,000
Step-by-step explanation:
First start defining variables for each of the salaries
Let M be the salary of the master's individual
Let B be the salary of the bachelor's individual
Given:
Average yearly salary of an individual whose final degree is a master's is $49 thousand less than twice that of an individual whose final degree is a bachelor's
can be translated into the equation
M = 2B - 49,000
Subtract M from both sides and add 49,000 to both sides:
49,000 = 2B - M
Switch sides:
2B - M = 49,000 [1]
Together they earned 116,000 becomes
B + M = 116,000 [2]
Add equations [1] and [2] to eliminate M
2B - M + B + M = 49,000 +116000
3B = 165000
B = 165000/3 = 55,000
Using equation 2, B + M = 116000 we get
55000 + M = 116000
M = 116000 - 55000 = 61,000
Solution
Bachelor's Degree: $55,000
Master's Degree: $61,000
true or false? in O radius OP intersects chord AC in point B so that AB = 8 units and BC = 8 units. This means that OP is perpendicular to AC
The answer is true, if radius OP intersects chord AC in point B and AB=8 units, BC=8 units.
What is meant by radius?The length of the line segments from a circle's center to its perimeter is referred to as the radius of a circle or sphere in more contemporary use. Radius has two possible plurals: the traditional English plural radiuses or radii. R or r is the most common radius abbreviation and mathematical variable name. Consequently, the diameter D is equal to double the radius.
Given,
In circle radius OP intersects chord AC in point B.
And AB=8 units, BC=8 units
So, OP is perpendicular to AC.
Due to the fact that OA and OC have equal sides and a base length of AC, OAC forms a triangle (the radius of the circle)
When you trace AC, you discover that O, a line perpendicular to AC, intersects the circle's center.
So, the answer is true.

The diagram shows a frustum which is constructed from a pyramid.
(a) The surface area of the frustum.
(b) Find the volume of the frustum.
(c) Find the surface area of the original pyramid.
The surface area of the frustum is 1744 square units
The volume of the pyramid is 2031.33 cube units.
What is a frustum of a pyramid?
By cutting the top of a typical pyramid, the frustum is created, which is a pyramid. Because of this, it is known as a truncated pyramid. The frustum of the pyramid is that portion of a pyramid that is cut through by a plane parallel to its base and lies between the vertex and the base.
a) First, we calculate the height of the frustum.
Let height be H
The base length be L1=24
Base width be W1=12
Top length is L2=14
To width be W2=13
Side height be C=13
Using the formula, H
[tex]H=\sqrt{ C^{2} - \frac{(L1-L2)^{2}}{2}}\\H=\sqrt{ 13^{2} - \frac{(24-14)^{2}}{2}}\\H=\sqrt{ 169 -50}\\H=\sqrt{119} \\H=11[/tex]
Now, the surface area of the frustum is LSA+area of bases of a frustum
Here, P1= perimeter of the base1 of the frustum
P2 is the perimeter of the base 2 of the frustum
[tex]L.S.A=\frac{1}{2} .(P1+P2).L \\=\frac{1}{2} .(72+42).24 \\=\frac{1}{2} .(114).24 \\=1368[/tex]
Now, S1 =area of base1 of frustum =288
S2= area of base 2 of frustum=98
TSA is given by LSA+area of bases of a frustum
=1368+288+98
=1724.
Therefore the surface area is 1724 square units.
b) Volume is given by
[tex]V=\frac{1}{3}.H.(S1+S2+\sqrt{S1S2} )\\ V=\frac{1}{3} . 11.(386+168)\\V=2031.33[/tex]

By solving a linear equation, we will see that they sold a total of 288 cookies.
How many cookies did they sell?An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenario. It is vital to note that an equation is a mathematical statement which is made up of two expressions that are connected by an equal sign.
We know that Phil and Matt sell cookies for $0.25 each, so, if they sell x cookies, the total revenue is: R(x) = $0.25*x
Now, we know that they made a total of $72.00, so now we need to solve the linear equation:
$0.25*x = $72.00x
= $72.00/$0.25 = 288

Which of the following could be an example of a function with a range (-∞, α) and a domain [b, ∞) where a > 0 and b>0?
Explanation:
Choices A and B are ruled out because they are cube root functions, which have a domain and range of "all real numbers".
Choice C is ruled out because the domain is [tex][a, \infty)[/tex]
To determine this domain, we set the radicand (aka stuff under the square root) to be greater than or equal to zero.
[tex]x-a \ge 0 \ \ \text{ solves to } \ \ x \ge a[/tex]
[tex]x \ge a \ \ \text{ turns into the interval notation } \ \ [a, \infty)[/tex]
The square bracket is used to include the value 'a' as part of the interval. This is the interval from x = a to positive infinity.
The domain of choice D is [tex][b, \infty)[/tex] found using similar steps as shown above.
The range is [tex](-\infty, a][/tex] since this square root function is decreasing, due to the negative out front, which means y = a the largest output possible. I recommend graphing it out using a tool like desmos or geogebra. These tools offer a way to use parameters.

Car sticker price =
Using the interest rates formula, we know that an automobile that costs $24588.44 is within our means.
What are interest rates?The amount of interest due each period expressed as a percentage of the amount lent, deposited, or borrowed is known as an interest rate.
The total interest on a loaned or borrowed sum is determined by the principal amount, the interest rate, the frequency of compounding, and the period of time the loan, deposit, or borrowing took place.
So, let's say the car's affordable price is P:
The entire payback is equal to P r/100 T + P.
In this case, P, r = 4.75, and T = 9 years.
$351,00 = P × (4.75/100 × 9 + 1)
$351,00 = P × ( 0.4275 + 1)
$351,00 = P × 1.4275
P = 351,00 / 1.4275
When you use the division operation, we receive:
P = $24588.44
Therefore, using the interest rates formula, we know that an automobile that costs $24588.44 is within our means.

Two quadrilaterals are similar quadrilaterals when the three corresponding angles are the same and two adjacent sides have equal ratios.
Therefore, quadrilaterals ABCD and JKLM are similar.
Hence, let's find the side x of the quadrilaterals.
Therefore,
CD / LM = BC / KL
CD = 5
LM = 2.5
BC = 3
KL = x
Hence,
5 / 2.5 = 3 / x
cross multiply
5x = 2.5 × 3
5x = 7.5
x = 7.5 / 5
x = 1.5

In the figure below L || M. find X
Answer:
x = 79
Step-by-step explanation:
To find the value of x we first need to find the missing angle of the triangle in the image.
The sum of interior angles in a triangle is equal to 180°.101 + 29 + missing angle = 180
Add like terms130 + missing side = 180
subtract 130 from both sidesmissing side = 50
Now, the sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle.
So the value of x:
29 + 50 = 79

to get the slope of any straight line, we simply need two points off of it, let's use those in the picture below.

Struggling on factoring quadratics. Could someone help me out with this worksheet, any examples of how to do the different types of problems would be great as well as finished problems
Answer:
When factoring, you want to get all of the terms on one side first and set all of it equal to 0. Many of the problems here are already in this format =0, but there are some where you'll have to move the terms around.
In these examples, it also looks like the highest power you have is x^2. This makes things easier to work with.
Let's just start with the first one, x^2 - 9x + 18 = 0.
We need to find two numbers that multiply to give us 18, and add together to give us -9. That would be -6 and -3.
-6 + -3 = -9
- 6 * -3 = 18
We can rewrite it now. This is the factored form.
(x - 6) * (x - 3) = 0
If you want to, you can go back to expanded form using the acronym 'FOIL'. First, Outside, Inside, Last. This refers to the order of multiplying the terms.
(x - 6) * (x - 3)
x * x = x^2
x * -3 = -3x
-6 * x = -6x
-6 * -3 = 18
Simplify
x^2 - 3x - 6x + 18 = 0
And we're back to where we started.
x^2 - 9x + 18 = 0
Hope this helps.
