I would solve for y on the top one and sub it into the bottom one.
y=-2x+8
(12/5, 16/5)
I believe the answe is 21 because the difference between x and y is 3x
They equal the same amount (3) but are written out in different ways.
Answer:
m=-6
Step-by-step explanation:
use slope formula to solve
m= rise/run=y2-y1/x2-x1
As the image is magnified by a factor of 1: 7(1/4)
= 1: (29/4)
= 4/29.
The length of x must've been also increased by a factor of 4/ 29.
Using this,
The scaled value of x will be,
3(4/29)
= 12/29 units.
