Answer:
y = - [tex]\frac{1}{4}[/tex] x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
To calculate m use the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (4, 6) and (x₂, y₂ ) = (- 4, 8)
m = [tex]\frac{8-6}{-4-4}[/tex] = [tex]\frac{2}{-8}[/tex] = - [tex]\frac{1}{4}[/tex], hence
y = - [tex]\frac{1}{4}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 4, 8 ), then
8 = 1 + c ⇒ c = 8 - 1 = 7
y = - [tex]\frac{1}{4}[/tex] x + 7 ← equation of line

Which graph represents a bike traveling at a constant rate of 12 miles per hour
The graph that represents the line (y = 12x) is option C) and this can be determined by using the point-slope form of the line.
Given :
Bike traveling at a constant rate of 12 miles per hour.
The following steps can be used to determine the graph that represents a bike traveling at a constant rate of 12 miles per hour:
Step 1 - All the graphs in the option pass through the point (0,0). So, (0,0) is the point through which a line is pass through.
Step 2 - Another point is (1,12) through which line passes because it is given that bike traveling at a constant rate of 12 miles per hour.
Step 3 - The equation of the line that passes through the points (0,0) and (1,12) is given by:
[tex]\dfrac{y-0}{x-0}=\dfrac{12-0}{1-0}[/tex]
y = 12x
So, the graph that represents the line (y = 12x) is option C).

darlene wants to buy martian invader video game. The video game price is $100. Darlene has a coupon for 25%. What is the price of the video game with the coupon?
Answer:
$75
Step-by-step explanation:
100 ÷ 25=75
Hope this helps!☺
To find the price of the video game with the coupon, subtract the discount amount from the original price.
Explanation:To calculate the price of the video game with the coupon, we first calculate the discount amount. The coupon is for 25% off, so the discount amount is 25% of $100. Using the formula discount = (percentage / 100) * original price, the discount amount is (25 / 100) * $100 = $25.
To find the price of the video game with the coupon, we subtract the discount amount from the original price. The price of the video game with the coupon is $100 - $25 = $75.
Therefore, the price of the video game with the coupon is $75.

(7+u)^2−(5+u)^2=6v, (2−v)^2−(6−v)^2=4u.
Solve for u in (7 + u)^2 - (5 + u)^2 = 6v
u = 3(v - 4)/2
Substitute u = 3(v - 4)/2 into (2 - v)^2 - (6 - v)^2 = 4u
8v - 32 = 6(v - 4)
Solve for v in 8v - 32 = 6(v - 4)
v = 4
Substitute v = 4 into u = 3(v - 4)/2
u = 0
Therefore,
u = 0
v = 4

P and a are on points on the line 4x+2y=8. What are the coordinates?
Answer:
The answer is P(0,4) , Q(2,0)
Step-by-step explanation:
Points P and A are any coordinates where y = 4 - 2x. For example, P might be the point (1, 2).
Explanation:The given equation is 4x + 2y = 8. To find the coordinates of points P and A, we can rearrange and simplify the linear equation. Divide the whole equation by 2, we get 2x + y = 4, or y = 4 - 2x. Therefore, the line has the slope-intercept form of y = mx + b, where m is the slope and b is the y-intercept. This line passes through all points (x, y) where y = 4 - 2x. Therefore, P and A can be any points satisfying this equation. For example, if x = 1, then y = 2, so one possible coordinate is P(1, 2).

Find the equation of the line below.
y=5x is your answer :)
The equation of the line passing through the points (1, 5) and (2, 10) is y = 5x.
Step 1: Calculate the slope (m) using the given points (1, 5) and (2, 10).
The slope (m) is given by the difference in y-coordinates divided by the difference in x-coordinates:
m = (10 - 5) / (2 - 1) = 5 / 1 = 5
Step 2: Select one of the points to use in the point-slope form. Let's choose (1, 5) as (x₁, y₁).
Step 3: Substitute the values into the point-slope form equation:
y - 5 = 5(x - 1)
Step 4: Distribute and simplify the equation:
y - 5 = 5x - 5
Step 5: Isolate 'y' on one side of the equation:
y = 5x - 5 + 5

Which segment is the image of AB reflected across the line y= -2
Answer:
GH
Step-by-step explanation:
If you look at y = -2, you can see that AB is one unit below it. Now if you flip this line segment across y = -2, all you have to do is count on unit up and find segment GH is in the correct position.
Answer:
The line segment GH is the answer.
Step-by-step explanation:
In the given figure we can see that point B of line AB lies one unit below the given y=-2. Now, when this line across y = -2, the point B will lie one unit above -2 that is H with the other end G.
So, GH is the correct answer.
What is the equation of the graphed function?
Enter your answer in the box.
f(x)=
F(x)=(x+1)^2 that’s the answer
Answer:
[tex]f(x)=(x+1)^2[/tex]
Step-by-step explanation:
We have been given graph of a function. We are asked to find the equation of the graphed function.
Upon looking at our given graph, we can see that the graph represents a parabola.
We know that vertex form of a parabola is: [tex]y=a(x-h)^2+k[/tex], where, (h,k) represents the vertex of parabola.
We can see that vertex of our given parabola is at point [tex](-1,0)[/tex], so substituting the coordinates of vertex of parabola, we will get:
[tex]y=a(x--1)^2+0[/tex]
[tex]y=a(x+1)^2[/tex]
Now we will find the value of a using coordinates of point (0,1) in above equation.
[tex]1=a(0+1)^2[/tex]
[tex]1=a(1)^2[/tex]
[tex]1=a*1[/tex]
[tex]1=a[/tex]
Therefore, the equation of our graphed function would be [tex]f(x)=(x+1)^2[/tex]
Find the values of x and y. Write your answer in simplest form.
Answer:
y = 6√3 and x = 6
Step-by-step explanation:
this is a 30-60-90 triangle. The side opposite the 30° angle corresponds to the side of length 1 in the most basic 30-60-90 triangle; the side opp. 60° to the side of length √3; and the hyp. to the side of length 2.
To find y, write and solve an equation of ratios, as follows:
adj side adj side (adjacent to the 30° angle)
y √3
hypo hypo then (cross multiplying): 2y = 12√3, and
12 2 y = 6√3
If the hypo here is 12 and the adj side (y) is 6√3, then we can use the Pyth. Theorem to find the third side (x):
[12]² = [6√3]² - x² ↔ 144 = 36(3) - x² ↔ 36 = x². So x = 6 here.
Answer:
x = 6
y ≈ 10. 40
Step-by-step explanation:
Using the SOHCAHTOA principle we can solve for x and y since the angle is known and it is a right angle triangle.
hypotenuse = 12
adjacent = x
opposite = y
cos 60° = adjacent/hypotenus
cos 60° = x/12
cross multiply
x = 12 cos 60°
x = 12 × 0.5
x = 6
Finding y
sin 60° = opposite/hypotenuse
sin 60° = y/12
cross multiply
y = 12 sin 60°
y = 12 × 0.8660254038
y = 10.392304845
y ≈ 10. 40

Complete the missing value in the solution to the equation.
(8,(8,left parenthesis, 8, comma
))right parenthesis
Answer:
The missing value is 5
The solution is (8,5)
Explanation:
The given equation is:
5x - 2y = 30
An order pair is written as (x , y). We are given (8 , ?)
This means that we want to find the y value that corresponds to x=8
To do this, we will substitute with x=8 in the given equation and solve for y
This is done as follows:
5x - 2y = 30
5(8) - 2y = 30
40 - 2y = 30
2y = 10
y = 5
This means that at x=8 and y=5, the equation is satisfied
(8,5) is a solution to the given equation
Hope this helps :)
Answer:
(8, 5)
Step-by-step explanation:
The given equation is:
5x - 2y = 30
We have to complete the given incomplete solution set (8, ?)
The first point in the ordered pair is always the x-value. So we are given an x-value and we have to find the corresponding y-value from the function.
Using x = 8 in the given function, we get:
5(8) - 2y = 30
40 - 2y = 30
- 2y = 30 - 40
- 2y = -10
y = 5
So, the value of y for x = 8 is 5. The complete ordered pair that satisfy the equation will be (8, 5)

A triangle has side lengths measuring 20 cm, 5 cm, and n cm. Which describes the possible values of n? 5 < n < 15 5 < n < 20 15 < n < 20 15 < n < 25
Answer:
15 < n < 25
Step-by-step explanation:
According to the triangle inequality theorem, any two sides lengths' sum should be greater than the third side. This also implies that to find the possible length of the 3rd side given other two sides (let two given sides be x and y), we can say that the 3rd side length will be between x+y and x-y.
Hence, we can say that n should be between 20+5 and 20-5.
So, 20 - 5 < n < 20 + 5, which is
15 < n < 25
This is the correct answer.
Answer:
15 < n < 25 which on ed is D
Step-by-step explanation:
According to the triangle inequality theorem, any two sides lengths' sum should be greater than the third side. This also implies that to find the possible length of the 3rd side given other two sides (let two given sides be x and y), we can say that the 3rd side length will be between x+y and x-y.
