How much metal to the nearest cubic inch with the railing contain?

you should pay $0.88

what is the image?

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
