represents the line of best fit for the distance (in feet) that Marcella traveled over time (in seconds) based on several races she ran.

Based on this equation, what is Marcella's average speed in feet per seconds?

Enter the answer as the correct value without units.

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
