Question

Solve -4x - 5 > -9 and describe the graph of the solution.

A: x > 1; closed circle on 1, shading to the right

B: x < 1; closed circle on 1, shading to the left

C: x < 1; open circle on 1, shading to the left

D: x > 1; open circle on 1, shading to the right

Answer 1

-4x - 5 > -9; add 5 to each side

-4x -5+5 > -9+5; simplify

-4x > -4 ; divide by -4 and switch the sign

-4x/-4 < -4/-4

x < 1 <-------Answer

To graph this it would be an open circle starting at 1 and an arrow going to the left
