Question

Which of the following graph of the compound inequality 4p+1>-7 and 6p +3 < 33

Answer 1

Explanation:

The first inequality has solution

4p > -8 . . . . . . subtract 1

p > -2 . . . . . . . divide by 4

This is graphed as an open dot at -2, with shading to the right.

Neither inequality symbol includes "or equal to", so both dots are open dots. The appropriate choice is the first one:

a number line with open circles at negative 2 and 5 with shading in between
