Answer: D
Step-by-step explanation:
To dilate by a scale factor of 5, multiply the x and y values of the points by 5
A(0,10) then A' would be (0,50)
Since 0 * 5 = 0 and 10 * 5 = 50
B(8,6) then B'(8*5,6*5) or (40,30)
C(4,2) then C'(4*5,2*5) or (20,10)
Answer:
x = 8.5
Step-by-step explanation:
Do solve this equation you will need to use the pythagorean theorem.
First start by plugging in the numbers.
The x will be what you are solving.
7 squared is 49 and 11 squared is 121.
Move the variable to one side. Do this by subtracting 49 from both sides.
Now find the square root of 72 in order to get rid of the x squared. (Convert to decimal if needed).
x = 8.5

First you have to realize that when x>0 y becomes = - 2*x for any value of x greater than 0. Also true is that the circle representing the end point is open. With those two facts, only top left and bottom right can be true. Of those 2, the answer is top left because the point at 0 is open.
the correct answer is c). y = 4x + 12. i just took the test for usa test prep
