Answer:
The skaters will collide at the points;
(2,28) and (4,24)
Step-by-step explanation:
The points they might collide will be the points when both y are equal;
-2x + 32 = -2x^2 + 18x
2x^2 -18x -2x + 32 = 0
2x^2 -20x + 32 = 0
2x^2 - 16x - 4x + 32 = 0
2x(x -8) -4( x -8) = 0
(2x -4)(x -8) = 0
2x = 4 or x = 8
x = 4/2 or x = 8
hence; x = 2 or 8
Now let’s get the y value
at x = 2, just substitute into any of the 2
y = -2x + 32
y = -2(2) + 32
y = -4 + 32 = 28
at x = 4
y = -2(4) + 32
y = -8 + 32
y = 24
The points that they will collide are;
(2,28) and (4,24)

Step-by-step explanation:
Answer:
A' ( 2, 4) and B' ( -4, 0)
Step-by-step explanation:
A ( -2, 4) and B( 4,0) reflected over the y-axis
A' ( 2, 4) and B' ( -4, 0)
the y-coordinate do not change and the x is opposite sign
(x,y) reflected over y-axis (-x, y)
I’m not sure if this is correct but here is a picture of what I think the answer might be. P.S my handwriting is not neat
Answer:
19/8
Step-by-step explanation:
8x-7=-12
8x=19
x=19/8
