8(v−4)+7v=−2
(8)(v)+(8)(−4)+7v=−2
8v+−32+7v=−2
(8v+7v)+(−32)=−2
15v+−32=−2
15v−32=−2
Add 32 to both sides.
15v−32+32=−2+32
15v=30
Divide both sides by 15.
15v/15=30/15
v = 2
Answer:
D. (x,y)-->(3x, 3y)
Step-by-step explanation:
Look at the x-values first. To get from -3 to -9, subtract 6. to get from you subtract 6 or multiply by 3. To get from 2 to 6 you add 4 or multiply by 3. To get from -1 to -3 you subtract 2 or multiply by 3. The answer is multiply by 3.
Because D is the only answer that all x-values get multiplied by 3, D is correct.
