10x + 2y = 2
- 5x = y + 10
Select the correct choice below and, if necessary, fill in the answ
Answers
Step-by-Step Explanation:
=> 10x + 2y = 2 (Eq. 1)
=> -5x = y + 10 (Eq. 2)
From Eq. 2 :-
-5x = y + 10
=> x = (y + 10)/-5 (Eq. 3)
Substitute value of ‘x’ from Eq. 3 in 1 :-
10x + 2y = 2
10(y + 10/-5) + 2y = 2
-2(y + 10) + 2y = 2
-2y - 20 + 2y = 10
0 = 10 + 20
=> 0 = 30
LHS is not Equal to RHS.

F(x)= -8x^5+4x^3+5x
Answers
Answer:
D) Function f is odd
Step-by-step explanation:
There are three ways to solve this problem:
Method 1
Recall that a function is even if [tex]f(x)=f(-x)[/tex] and odd if [tex]-f(x)=f(-x)[/tex] for all x. Hence, we evaluate [tex]f(-x)[/tex] to check if the function is even, odd, both, or neither:
[tex]f(x)=-8x^5+4x^3+5x\\\\f(-x)=-8(-x)^5+4(-x)^3+5(-x)\\\\f(-x)=8x^5-4x^3-5x[/tex]
Here, we can see that the signs of the original terms switched to their opposite operations, so it is clear that [tex]-f(x)=f(-x)[/tex], which tells us that the function is odd.
Method 2
A function is odd if it has symmetry about the origin, and even if it has symmetry about the y-axis. We can clearly see on the graph there is origin symmetry, so the function is odd.
Method 3
A function is even if every term in that function has an even degree, or odd if every term has an odd degree. We can see that the degrees of each term are odd, so we can conclude that the function is odd.

someone please help me and solve for the unknowns and give reasons please
or can you just solve for the unknowns please
Answers
Answer:
Step-by-step explanation:
The angles labeled with 2x, 4x, and 3x are on a straight line so their sum is equal to 180
2x + 4x + 3x = 180 add like terms
9x = 180 divide both sides by 9
x = 20
The angle represented with 3x - 30 and the angle represented with 2x + 10 are alternate and their measurement is same
3x - 30 = 2x + 10 export like terms to same side of the equation
3x - 2x = 10 + 30
x = 40
to find the angles replace x with the value found for each.

In mathematics, a function is a rule that gives each input value in a set a distinct output value. A function is, more precisely, a collection of ordered pairs (x, y), where each x-value is matched with precisely one y-value.
The variable x normally represents the input values, also known as the independent variable, while the variable y typically represents the output values, also known as the dependent variable. Typically, a symbol like f(x), where f is the function's name and x is the input variable, is used to represent a function.

The interest rate which is required in order for Leah to end up with $40,000 in his account which is compounded daily, is 4.11%.
What is compound interest?Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.
The formula for the final amount with the compound interest formula can be given as,

A triangular prism that has a volume of 24 cubic inches is changed by a scale factor of 5. Find the volume of the dilated cube.
A. 120
B. 600
C. 3000
D. 3600
Answers
==========================================================
Reason:
If the linear scale factor is 5, then the volume scale factor is 5^3 = 125
Meaning we'll multiply the old volume by 125 to get the new volume
new volume = 125*(old volume)
new volume = 125*(24)
new volume = 3000
---------------
A more in-depth look:
Consider a 2 by 2 by 2 block. Its volume is 2*2*2 = 8
Now multiply each dimension by 5, so we now have a 10 by 10 by 10 block. The new larger volume is 10*10*10 = 1000
The volume ratio is 1000/8 = 125, which matches with the value found earlier.
Since we multiplied each piece by 5, and did so three times, we're really multiplying the volume by 5*5*5 = 125.

Building a Storage Container
You are being asked to design an enclosed water storage container. You are given a budget of
$100 to build the container. It has been determined that the best material to make the container
costs $10 per m². (In other words your surface can not cost more than $100.) What is the
largest amount of water your container can hold? You will need to explain to your boss the
reasoning because they have a business degree and do not really remember any of their
geometry work from school.
Answers
Answer:
2973.5 liters
Step-by-step explanation:
You are being asked to find the volume of the largest possible container that has a given surface area. The volume will depend on the shape. If shape is not specified, we know a sphere has the largest volume for a given area.
__
areaThe available area is ...
($100) / ($10/m²) = 10 m²
diameterThe area of a sphere with diameter d is ...
A = πd²
Then the diameter for the given area is ...
10 m² = πd²
(10/π) m² = d² . . . . . divide by π
√(10 m²/π) = d ≈ 1.78412 m . . . . . . diameter of the largest sphere
volumeThe volume of a sphere is given by ...
V = 4/3πr³ = (π/6)d³
For the diameter found above, the volume of the sphere will be ...
V = (π/6)(1.78412 m)³ ≈ 2.97354 m³
There are 1000 liters in a cubic meter, so the largest amount of water that can be contained is ...
2.97354 m³ × (1000 L/m³) = 2973.54 L
The largest amount of water the container can hold is about 2973.5 liters.

The solution to this equation is p = -6
This expression is related to a First Degree Equation.First degree equation is a mathematical expression and sentence, which is defined by having only one unknown. Its representation is given by: ax+b=0.
— To solve this expression, let's eliminate these square root symbols:
√-5p = √24-p
-5p = 24 - p
— Move the p term before the positive sign equality, thus also shifting the 24th term:
-5p = 24 - p
-5p + p = 24
-4p = 24
— Finally, let's divide the second to the first term of this equation:
-4p = 24
p = 24 ÷ (-4)
p = -6
Therefore, the correct result of this expression will be p = -6

What is the area of a triangle whose vertices are R(3, 4), S(6, 2), and T(7, 10)?
Enter your answer in the box.
Answers
According to Heron's formula, the area of a triangle whose vertices are R(x, y) = (3, 4), S(x, y) = (6, 2) and T(x, y) = (7, 10) has a value of approximately 14.525 units.
How to calculate the area of a triangle by knowing its sides
In this question we must determine the lengths of the three sides of the triangle by Pythagorean theorem and then the area is determined by Heron's formula.
First, we determine the length of each side:
[tex]RS = \sqrt{(6-3)^{2}+(2-4)^{2}}[/tex]
[tex]RS = \sqrt{3^{2}+(-2)^{2}}[/tex]
[tex]RS = \sqrt{13}[/tex]
[tex]ST = \sqrt{(7-6)^{2}+(10-2)^{2}}[/tex]
[tex]ST = \sqrt{1^{2}+8^{2}}[/tex]
[tex]ST = \sqrt{65}[/tex]
[tex]RT = \sqrt{(7-3)^{2}+(10-4)^{2}}[/tex]
[tex]RT = \sqrt{4^{2}+6^{2}}[/tex]
[tex]RT = \sqrt{80}[/tex]
Now we calculate the area of the triangle by Heron's formula:
[tex]s = \frac{\sqrt{13}+\sqrt{65}+ \sqrt{80}}{2}[/tex]
s ≈ 10.306
[tex]A = \sqrt{10.306 \cdot (10.306 - \sqrt{13})\cdot (10.306 - \sqrt{65})\cdot (10.306 - \sqrt{80})}[/tex]
A ≈ 14.525
According to Heron's formula, the area of a triangle whose vertices are R(x, y) = (3, 4), S(x, y) = (6, 2) and T(x, y) = (7, 10) has a value of approximately 14.525 units.

Answer:
Yes
Step-by-step explanation:
So we know the second child was a boy however if the first child was a boy, the probability of getting a second boy would be 7/17 since one boy is missing and one person is missing from the total.
However, if a girl was chosen as the first child, the probability of getting a boy second would be 8/17 since no boys would be missing but one person would be missing from the original total.

The solution set is {-6, -2}.
Step-by-step explanation:
x^2 + 8x + 15 = 3
x^2 + 8x = -12
Completing the square:
(x + 4)^2 - 16 = -12
(x + 4)^2 = 4
Taking square roots of both sides:
x + 4 = +/- 2
x = 2 - 4 = -2 or x = -2-4 = -6.

The value of 5 in 13.725 is 0.005 (or 5 in the thousandths place)
We need to find numbers with 10 times that value in the number.
0.005 x 10 = 0.05 (or 5 in the hundredths place)Evaluating the options given :
(a) 5.368
The value of 5 in this number is 5 in the unit place (No ×)(b) 12.459
The value of 5 in this number is 5 in the hundredths place (Yes √)(c) 57.31
The value of 5 in this number is 5 in the tens place (No ×)(d) 6.508
The value of 5 in this number is 5 in the tenths place (No ×)(e) 4.315
The value of 5 in this number is 5 in the thousandths place (No ×)(f) 7.65
The value of 5 in this number is 5 in the hundredths place (Yes √)Hence, the numbers are : (b) 12.459 and (f) 7.65
Answer:
b and f
Step-by-step explanation:
The 5 in 13.725 is in the thousandth place: 0.005
So three places after the decimal point.
If you multiply 0.005 by 10, then it becomes 0.05 (as multiplying by 10 moves the decimal point one place to the right).
Therefore, we are looking for numbers that have a 5 in the hundredth place, so a 5 in the second place after the decimal point.
There are two numbers that have a 5 in the hundredth place:
(b) 12.459
(f) 7.65
