Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 5x + 4 ( subtract 4 from both sides )
y - 4 = 5x ( divide both sides by 5 )
= x
Change y back into terms of x
(x) =
If x = 3 units, y = 13 units, and h = 7 units, then what is the area of the trapezoid shown above?
