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.
Is it -6? that’s what it looks like but i’m not 100% sure
Answer: a = -3
Step-by-step explanation: First we distribute the -2 to a and -3 to get -2a+6=12, then subtract 6 on both sides, -2a=6, finally divide by -2 on each side to get a = -3.

Step-by-step explanation:
(3x-11)+(2x+11)+2y = 180
5x+2y = 180
(3x-11)+(2x+11)=2y
5x = 2y
x = 18
y = 45
