Step-by-step explanation:
Answer:
one solution, y=0, x = 1.5
Step-by-step explanation:
3y = -6x + 9
y = -6x +9
Since x - 3 < 0 for -2 < x < 3, |x-3| = -(x-3)
Since x + 2 > 0 for -2 < x < 3, |x+2| = x+2
Since x - 5 < 0 for -2 < x < 3, |x-5| = -(x-5).
So y = -(x-3) + (x+2) -(-(x-5)) = 3 - x + x + 2 + x - 5 = x.
y = x, if -2 < x < 3.
22cm is the greatest
It should be greater than17(20-3)
and smaller than 23(20+3)
