What is the average rate of change for this function for the interval from x= 1

Usimov [2.4K]

Answer:

C. 8

Step-by-step explanation:

The average rate of change is the slope of the line between the two points of interest. It is given by the formula ...

m = (y2 -y1)/(x2 -x1)

For points (1, 2) and (3, 18), the average rate of change is ...

m = (18 -2)/(3 -1) = 16/2 = 8

The average rate of change between x=1 and x=3 is 8.

How could you solve for x in the problem 3x+7=-x-1

lukranit [14]

Hello there!

$3x+7=-x-1\\$

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓

First you had to subtract by 7 from both sides of the equation.

$3x+7-7=-x-1-7$

Simplify

$3x=-x-8$

Then you add by x from both sides of the equation.

$3x+x=-x-8+x$

Simplify

$4x=-8$

Divide by 4 from both sides of the equation.

$\frac{4x}{4}=\frac{-8}{4}$

Simplify it should be the correct answer.

$x=-2$

Answer⇒⇒⇒x=-2

Hope this helps!
