Answer:
x=3; y=3
Step-by-step explanation:
y = -1/2 x + 9/2
so if we multiply by 2 on both sides
2y = -x + 9
and we know that y = 3x-6
so we get
2(3x-6)=-x+9
6x-12 = - x + 9
7x = 21
x = 3
y = 3 * 3 - 6
y=3

x=3, y=3
You put them in the equation and they should work.

Since the origin is the center of the dilation, this means we simply multiply every coordinate of the given point by the scale factor.
(6,12) would turn into (18,36) since
6*3 = 18
12*3 = 36
The final answer is (18,36)
Answer:
x=-7.88
y=-32.35
the point answer would be (-7.88 , -32.35)
Step-by-step explanation:
First step is to multiply 3x+y=-56 by 4 and you get 12x+4y=-224
Then add each equation together to eliminate y from each equation. You get 17x=-134
Then find divide that equation by 17. You would get x=-7.88
Then plug -7.88 into one of the original equations for x. 5(-7.88)-4y=90 And from that you get -39.4-4y=90
Then isolate the y variable. You would get -4y=129.4
Then divide by -4 and get y=-32.35
