Need help plz very much

Answer:

Step-by-step explanation:

Remember that when we are dividing two exponents with the same base (here, it's 13), we can subtract the values of the powers:

$\frac{a^m}{a^n} =a^{m-n}$

So, here, we have $\frac{13^{10}}{13^7}$ , so we subtract 7 from 10:

$\frac{13^{10}}{13^7}=13^{10-7}=13^3$

Thus, 3 should go in the box.

Write an equation that describes the line that passes through (2, 2) and (0, -3).

gtnhenbr [62]

Answer:

f(x) = $\frac{5}{2}$ x

Step-by-step explanation:

The first thing we need to find is the slope of the line able to pass through the given two points. Right now we have y = mx + b (linear function equation) and we need to find m.

Using the slope formula or $m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}$ and plugging in the given points' x and y values:

$\frac{-3-2}{0-2}$ = $\frac{-5}{-2}$ = $\frac{5}{2}$

The slope of the line is that for every 5 units the line goes upwards, it goes 2 units to the right.

Our equation is now y = $\frac{5}{2}$ x + b. If you were in need of it, b gives the line's y-intercept, the place where it hits the y-axis. In this case you do not need b because the only specified conditions in the problem are the units the line hits.

Our final equation is:

f(x) = $\frac{5}{2}$ x
