5x - 8 = y
When y = 1,
5x - 8 = 1
Add 8 to each side of the equation:
5x = 9
Divide each side by 5:
x = 9/5 = 1.8

x = 8y = 6(5x8) + (3x6) = 58(5x8) - (3x6) = 22
What is the area bounded by the graph of the function f(x)=1-e^-x over the interval [-1, 2]?
y=1/3x+3
It is 1.2164
If you plug in y for the x function, and it equals the answer you got, it is right.
