In order to find the solution of the given compound inequality, solve each inequality for x, as follow:

4x - 5 < -1 add 5 both sides

4x < -1 + 5

4x < 4 divide by 4 both sides

x < 4/4

x < 1

2x - 3 ≥ -9 add 3 both sides

2x ≥ -9 + 3

2x ≥ -6 divide by 2 both sides

x ≥ -6/2

x ≥ -3

Hence, the interval solution of the compound inequality is [-3 , 1)

The solution on the number line is shown below:
