Answer:
[tex]y=x+3[/tex]
Step-by-step explanation:
Using Point-Slope form: Y-y1=m(X-x1)
Slope(m) = 1, Point(x1,y1) = (-2,1)
y-1=1(x+2)
y=x+2+1
y=x+3

My brain can’t think straight and I’m trying to figure out the difference in the solution to a graph of a linear equation and the solutions to the graph of a linear inequality
For a linear equation the solutions are on the line, while for inequalities the solutions are above or below the line (sometimes the line is also included).
What are the differences?When we have a linear equation of the form:
y = line
The solutions on the graph of this equation are the points on the line.
Now, for inequalities like:
y > line
or
y < line.
The solutions are all the points above (or below) the line itself.
Finally, for inequalities like:
y ≥ line
y ≤ line
The solutions are above (below) the line and the line itself.

Estelle and Carlos will be hosting a party and will buy 6 pies for their guests. Two lemon meringue pies cost $3 less than 4 blueberry pies. Three lemon meringue pies cost$9 more than 3 blueberry pies. How much does each type of pie cost?
The cost of each lemon meringue pie is $7.5 and the cost of each blueberry pie is $4.5.
Given that, Estelle and Carlos will be hosting a party and will buy 6 pies for their guests.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the cost of lemon meringue pies be L and the cost of blueberry pies be B.
Now, 2L = 4B - 3 and 3L= 3B + 9
Multiply the equation 2L = 4B - 3 by 3
6L = 12B - 9 --------(I)
Multiply the equation 3L= 3B + 9 by -2
-6L = -6B - 18 --------(II)
Add equation (I) and (II)
6L+(-6L) = 12B - 9 + (-6B-18)
⇒ 0 = 6B - 27
⇒ 6B = 27
⇒ B = $4.5
So, cost of lemon meringue = 2L = 4×4.5 - 3
⇒ 2L = 18 - 3
⇒ 2L = 15
⇒ L = $7.5
Therefore, the cost of each lemon meringue pie is $7.5 and the cost of each blueberry pie is $4.5.

You can find an equation for the temperature in
degrees Celsius for a given temperature in
degrees Fahrenheit by finding the function's?
-15° = C is a given temperature in degrees Fahrenheit by finding the function's.
What is the purpose of Fahrenheit?
Temperature measurements are made in Fahrenheit. It is based on the Fahrenheit scale, which was first put forth by physicist Daniel Gabriel Fahrenheit in the 1700s. According to the Fahrenheit scale, water has a boiling temperature of 212 degrees Fahrenheit, while ice melts at 32 degrees.Water freezes at 32 degrees Fahrenheit and boils at 212 degrees on the Fahrenheit temperature scale. The sign ° F is used to denote it.we have a value for F, and so we use that to find C. Insert F's value into the equation:
5 = 9/5 C + 32
Subtract 32 from both sides:
5 - 32 = 9/5 C + 32 - 32
-27 = 9/5 C
Now we multiply both sides by 5/9
-27 * 5/9 = 9/5 C 5/9
-27 is divisible by 9:

Consider the equation:24 = x^2 - 4x + 31) Rewrite the equation by completing the square.Your equation should look like (x + c)^2 = d or (x – c)^2 = d.[ ]2) What are the solutions to the equation?Choose 1 answer:A) x=2 ± 5B) x = -2 ± √5C) x = 2 ± √5D) x = -2 ± √5
(x - 2)² = 25
Explanation:24 = x² - 4x + 3
rewritting:
x² - 4x = 24 - 3
x² - 4x = 21
using the completing the square:
coefficient of x = -4
square half the coefficient of x = (-4/2)² = (-2)²
Add the square half the cofficient of x to both sides of the equation
x² - 4x + (-2)² = 21 + (-2)²
taking out -4x:
(x - 2)² = 21 + 4
(x - 2)² = 25
The equation above is in the form (x + c)^2 = d or (x – c)^2 = d

DROP DOWN 1?
Answers:
Slope intercept equation is y = -4x - 17
The point (-6, 7) is on the graph of the line.
====================================================
Explanation:
Let's solve for y
y - 7 = -4(x+6)
y - 7 = -4x - 24
y = -4x - 24 + 7
y = -4x - 17
It is now in slope intercept form y = mx+b
m = -4 = slope
b = -17 = y intercept
---------------
Compare the equation y - 7 = -4(x+6) with the point-slope form of y-y1 = m(x-x1)
The (x1,y1) is a point the line goes through.
Rewriting x+6 into x-(-6) has us get y - 7 = -4(x-(-6))
We can see that x1 = -6 and y1 = 7
Therefore, the point (x1,y1) = (-6,7) is on the line.

What is the Alternate Exterior Angles Theorem?When two parallel lines are intersected by a transversal, the exterior angles created on either side of the transversal are equal, according to the alternate exterior angle theorem.
The given angles are 2x + 19° and x + 23°.
As these pair of angles are created on the outer side of the parallel lines but on the other side of the transversal, they are alternate exterior angles.
Using the Alternate Exterior Angles Theorem,
2x + 19° = x + 23°

Hillsboro Street and Manchester Avenue intersect. If the diagonal distance across the
intersection is 73 feet and Hillsboro Street is 55 feet wide, how wide is Manchester Avenue?
The intersection's two opposing corners are 91.40 feet apart.
Since the given data are:
Width of the Hillsboro Street = 73 feet
Width of Manchester Avenue = 55 feet
When Hillsboro Street and Manchester Avenue cross, calculate the distance between the intersection's two opposing corners,
Because the junction of Hillsboro Street and Manchester Avenue created a right-angled triangle:
Using Pythagoras's Theorem,
H² = B² + P²
H² = (55)² + (73)²
H² = 3025 + 5329
H² = 8354
H = √8354
H = 91.40
As a result, the distance between the intersection's two opposing corners is 91.40 feet.

What is basic division?Long division is a common division procedure in mathematics that may be used to divide multi-digit Hindu-Arabic numbers (Positional notation) and is easy enough to do manually. A division problem is divided up into a number of simpler steps.
Like in every division problem, the dividend and divisor are two numbers that are divided to produce the quotient, which is the final product. It makes it possible to carry out computations involving arbitrary large numbers by adhering to a set of straightforward processes. When the divisor contains only one digit, long division is nearly always avoided and instead, the condensed version, known as short division, is employed. A less mechanical approach to long division is known as "chunking," which is also known as the "partial quotients method" or "hangman method."

Given : To make 12 biscuits Hamza needs ; 375g of butter

The value of y in the equation 1/2 = 1/4y + 1/8 when solved is: y = 3/2(three halves).
How to Solve an Equation?Solving an equation implies looking for the value of the variable that would make the equation true or balanced if we plug in the value of that variable into the equation.
To solve for the value of y in the given equation, 1/2 = 1/4y + 1/8, isolate the variable of equation, y, to one side.

What is rectangle ?
It is a common geometrical shape having 4 sides and four vertices and each side making 90 degree with the adjacent side.
Surface area of rectangle is given as :
s = 2(lb+bh+hl)
Volume of rectangle is given as :
V= lbh
Area of rectangle is given as ;
A = lb
If a rectangular photo measures 18cm by 7cm initially, the area of the photo before enlargement will be expressed as :
A1 = Length * breadth
A1 = 18 x 7
A1 = 126 cm²
If the photo is enlarged in the ratio 2:3 then increase/decrease in length and breadth will be :
2 : 3 = 2/3 = 0.66
This is 33% decrease of its dimensions’ measurements.
Length of the photo after decrement = 18 x 2/3 = 12 cm
breadth of the photo after decrement = 7 x 2/3 = 4.66 cm
Area of the decreased photo A2 = 12 x 4.66 cm² = 55.92 cm²
The ratio of the area of the original photo to the area of the enlarged photo = A1/A2 = 126 / 55.92

The equation of the graph after the translation is h(x)=f(x)+6
The process of transforming an equation or existing graph into a new graph is known as graph translation.
Changing algebraic equations is a typical algebraic problem. A translation modifies the graph of a parent function. Dilations, reflections, and translations are the three distinct types of translation.You can adjust a function's x values horizontally or its y values vertically (affects the x-values).We understand that in order to represent the translation by the predetermined amount, the x- and y-coordinates must be changed.Since the graph for h(x) has moved to the left by 6 units as we can see in the graph. Hence the co-ordinates will also change by 6 units . hence the graph is translated to the left by 6 units.
Therefore the equation after the translation is given by h(x)=f(x)+6 .
