RE
Which expression is equivalent to -2-7?
-2+(-7)
-2-(-7)
2-7
2+7

-2+(-7)= -2-7

Step-by-step explanation:

Let's cross out the ones that are wrong.

-2+(-7)  -> The - on the 7 overpowers the addition sign.

-2-(-7) = -2+7

2-7  -> This doesn't have a negative in front of the 2.

2+7= This doesn't have a negative in front of the 2.

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
