What is the anser to the equation 2^{2x+2} = 2^{3x}

Marianna [84]

Answer: C) x = 2

2^{2x + 2} = 2^{3x}

Since both terms (above) have the same base, set the exponents to be equal:

2x + 2 = 3x (Rearrange to solve for x)

x = 2

∴ x = 2

What is the slope of the line in the graph?<br>4th possible answer is 4/3<br>----<br>بنام<br>

Delvig [45]

Answer: Second option.

Step-by-step explanation:

The slope of a line can be calculated with this formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Then, you need to choose two points of the line shown in the graph and substitute them into the formula for calculate the slope:

Let's pick the points (-4,4) and (4,-2).

Substituting:

$m=\frac{-2-4}{4-(-4)}$

Simplifiying, you get that the slope of the line in the graph is:

$m=\frac{-2-4}{4-(-4)}\\\\m=\frac{-6}{4+4}\\\\m=\frac{-6}{8}\\\\m=-\frac{3}{4}$
