C) y= -x+5
explain:
y-2=-x+3
y= -x+3+2
so y= -x+5
Answer:
57/200 Km
Step-by-step explanation:
3/10*10= 30/100
30/100+27/100=57/200km
Answer: 7 Courts
Step-by-step explanation: One US gallon equals for US courts, so 1 3/4 x 4 is seven
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)
54% = 54/100 = 27/50
Answer: 27/50
