What is the answer of 10 to the power of -4 [tex] 10^-4

malfutka [58]

Remember
$x^{-m}= \frac{1}{x^m}$

so

$10^{-4}= \frac{1}{10^4}= \frac{1}{10000}=0.0001$

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

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:

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