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)

Order of Operations is what you have to use
Hi Malik.
2x+4>14 or -(2x+4)>14
solve each inequality individually
you get
x>5 or x<-9
Answer: reflection across the x-axis
vertical shrink by a factor of 1/2
horizontal shrink by a factor of 1/3
vertical shift up 4 units
<u>Step-by-step explanation:</u>
The transformed function has the following:
Negative: reflection across the x-axis
A = 1/2 vertical shrink by a factor of 1/2
B = 3 horizontal shrink by a factor of 1/3
C = 0 no horizontal shift
D = 4 vertical shift of 4 units up
