The answer is 5663588 for your question
-4m-24=-8
(add 24 to both sides)
-4m=16
(divide by -4 on both sides)
m=-4
Answer: second option.
Step-by-step explanation:
Given the transformation →
You must substitute the x-coordinate of the point A (which is ) and the y-coordinate of the point A (which is ) into to find the x-coordinate and the y-coordinate of the image of the point A.
Therefore, you get that the image of A(2,-1) is the following:
You can observe that this matches with the second option.
for 1st
use the formula of inlargement
A(x,y)when enlarging by scale factor k gives A'(kx,ky)
for 2nd
a=
(2a+3)-(a-5)(2a+2)+a^2
b=
3y(7y-8)
5/8 inches longer since 8/8 - 3/8 = 5/8
