What is the difference quotient of the function g(x) = 4^x

lidiya [134]

Answer:

First choice

Step-by-step explanation:

The difference quotient in general is $\frac{g(x+h)-g(x)}{h}$ . To get an expression for $g(x+h)$ , replace x with x + h.

For this question,

$\frac{4^{x+h}-4^x}{h}=\frac{4^x\cdot4^h-4^x}{h}$

Factor $4^x$ out of the numerator.

$\frac{4^x(4^h-1)}{h}$

Pls help me with the inverse operation of this problem. Best answer gets brainliest

timurjin [86]

Answer:

x=7

Step-by-step explanation:

I believe we are solving for x. In that case, let us start by moving 1 to the other side.

$\frac{4(x+3)}{5} = 8$

Now, we want to get rid of that denominator of 5. Let us multiply both sides by 5:

$4(x+3)=40$

Now, we may divide both sides by 4 to get rid of the coefficiant:

$x+3=10$

When we subtract both sides by 3, we get

x=7

<em>I hope this helps! :)</em>

What is the value of x?

frez [133]

$\left\{\begin{array}{ccc}x+2y=4&\text{multiply both sides by 5}\\4x-5y=42&\text{multiply both sides by 2}\end{array}\right\\\\\underline{+\left\{\begin{array}{ccc}5x+10y=20\\8x-10y=84\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad13x=104\qquad\text{divide both sides by 13}\\\\\boxed{x=8}\\\\Answer:\ \boxed{\boxed{x=8}}$
