The disctance between -8 and 5 on the number line can be found by which expression??

1 answer:

5 0

It's A. First of all, one of the only 2 things in math that will NEVER be negative is distances/lengths and times. You have a distance here, so because one of your 2 numbers is negative, you have to take the absolute value of the difference. -8-5 = -11, but the absolute value of that is 11. Put the numbers on a number line and count the units between -8 and +5 and there are 11 units between those 2 numbers.

Answer:

$\Huge \boxed{-2}$

Step-by-step explanation:

$f(x)=-2x^2-2x+10$

For f(2), the input of the function is 2.

Let x = 2.

$f(2)=-2(2)^2-2(2)+10$

Evaluate.

$f(2)=-2(4)-2(2)+10$

$f(2)=-8-4+10$

$f(2)=-2$
