Answer 1

Hello!
A. 5-4x<-7
Subtract 5
So then you get = -4x< -12
However, the sign is negative so you change it, giving you -4x>-12
Now you divide= x>3
B. The graph will go to the right with an open circle on the three.

1. 5x + 6 <= -9 (Remember >= means greater than or equal to) a. Solve the inequality showing all steps and b. Describe the graph. (Guide: open or closed circle on what number, arrow to the right or left.) 2. Solve the equation showing all steps. 7x +5 = -x - 11 3.
