What does -2 raised by 10 equal to?

I think "raised by ten" is trying to say add 10. So for this you would write an expression based on the information provided.

-2 + 10 = ?

A simple way to solve this problem would be to switch the numbers. Now this only applies to this situation where the negative number is before the positive number.

10 + (-2) = ?

Now you will just take out the addition signs and keep the minus.

10 - 2 = 8

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3
