Answer:

y was not substituted for every x

Step-by-step explanation:

To find the inverse of ...

y = f(x)

you need to solve ...

x = f(y)

Here, f(x) = x^2 +12x, so f(y) = y^2 +12y

This is not the expression we see on the right of ...

x = y^2 +12x

Apparently y was not properly substituted into f(x).

What is the sum of measures of the exterior angles of a polygon that has fifteen sides

madreJ [45]

$\bf \textit{sum of exterior angles}\\\\ n\theta =360~~ \begin{cases} n=\textit{number of sides}\\ \theta = \textit{angle in degrees}\\[-0.5em] \hrulefill\\ n=15 \end{cases}\implies 15\theta =360 \\\\\\ \theta =\cfrac{360}{15}\implies \theta =24$

4/5 N= 2/3. N = ? 2/15 5/6 1 1/5 1 7/15

Verizon [17]

Answer:

N = 5/6

Step-by-step explanation:

4/5 N= 2/3. Find N (solve for N).

Isolate N. To do this, multiply both sides of the equation by (5/4):

(5/4)(4/5)N= (5/4)(2/3)

becomes N = 10/12, or N = 5/6.

Help me solve this 3-p/(-4) if p =12

kvv77 [185]

Since ur using 12 as p we solve it now.

3 - 12 over -4 = 6

Move the negative sign to the left (3 - (-12/4)
Simplify 12/4 to 3 ( 3 - (-3)
simplify brackets (3 + 3)
finally the answer is 6
