Answer:

n = 5

Step-by-step explanation:

Given

5n + 20n = 5(n + 20), that is

25n = 5(n + 20) ← divide both sides by 5

5n = n + 20 ( subtract n from both sides )

4n = 20 ( divide both sides by 4 )

n = 5

What is the inverse of -9x+2
horsena [70]

Step-by-step explanation:

so,

y = -9x + 2

now we need to transform this equation that actually x is calculated out of y.

and then, at the end, to make the inverse function a formally correct function, we rename x to y and y to x.

so,

y = -9x + 2

y - 2 = -9x

x = -(y - 2)/9 = (-y + 2)/9

=> for a formal function definition

y = (-x + 2)/9
