Answer:

7/12

Step-by-step explanation:

The problem is asking for the <em>total</em> amount, so you add both fractions. Because both fractions have common denominators, you can just add the numerators (the top numbers of the fractions) to get your answer. 4 + 3 = 7. So, black and horses run a total of 7/12 miles. Hope this helped!

What is the slope of the line that passes through the points (-2, 2), and (-4, -2)? - 2 -2

dusya [7]

The formula of a slope:

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

We have the points (-2, 2) and (-4, -2). Substitute:

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

<h3>Answer: the slope = 2</h3>

PLEASE ANSWER ASAP

Vlada [557]

Answer:

Step-by-step explanation:

For an inverse function you take f(x) and turn that to y then you switch x and y. So you should start off with y= 5x -8. so then you switch x and y so x= 5y - 8. So then you solve. You subtract 8 from both sides and divide by 5 and you get F(x) inverse = x + 8/5
