Mathematics
1 answer:
mestny [16]3 years ago
8 0

Answer:

x=7, y=9. (7, 9).

Step-by-step explanation:

-3x+y=-12

5x-2y=17

---------------

y=-12-(-3x)

y=-12+3x

y=3x-12

5x-2(3x-12)=17

5x-6x+24=17

-x+24=17

-x=17-24

-x=-7

x=7

y=3(7)-12

y=21-12

y=9

Snezhnost [94]

9514 1404 393

Answer:

  A'(14, 2)

Step-by-step explanation:

The y-value of A is the same as the y-value of the center of dilation, so it remains unchanged.

The x-value of A is 4-(-1) = 5 units from the center of dilation, so A' will be 15 units from the center of dilation. 15 +(-1) = 14. The coordinates of A' are (14, 2).
