Use pythagorians theorem a^2 + b^2 = c^2. 4^+20^ = 20.40 feet. The ladder is 20.40 feet long.
Step-by-step explanation:
y - 4x = 3
Writing in slope intercept form that is y = mx + c
y = 4x + 3
Hope it will help :)
Answer:
(x) =
Step-by-step explanation:
let y = f(x), then rearrange making x the subject
y =
x + 4 ( subtract 4 from both sides )
y - 4 =
x ( multiply both sides by 5 to clear the fraction )
5y - 20 = x
Change y back into terms of x with x =
(x) , then
(x) = 5x - 20
