Replace g(x) with y

y=4x−7

Interchange the variables.

x=4y−7

Solve for y

.y=7/4+x/4

Solve for y

and replace with g−1(x)

g−1(x)=7/4+x/4

Sorry if I am wrong I am truely

Simplify the following expression.

Sloan [31]

Answer: $3x^{2}+12x$

Step-by-step explanation:

1. To solve simplify the expression given in the problem, you must apply a property of exponents called Quotient of powers, which states that when you divide two powers that have the same base, you must subtract the exponents.

2. Keeping this property on mind, you can rewrite the expression as following and simplify:

$\frac{-12x^{3}}{-4x}-\frac{48x^{2}}{-4x}=3x^{2}+12x$

The volume of the cylinder is 5275 ft and the height is 23 find the diameter please explain this is for school tomorrow

stepan [7]

$\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\ \cline{1-1} V=5275\\ h=23 \end{cases}\implies 5275=\pi r^2(23)\implies \cfrac{5275}{23\pi }=r^2 \\\\\\ \sqrt{\cfrac{5275}{23\pi }}=r\implies 15.144\approx r~\hspace{10em}\stackrel{diameter=2r}{d\approx 30.288}$
