Question

Which inequality has the solution z < -4?

z + 4 < 0

z – 4 < 0

z + 3 < 1

z – 3 < 1

Answer 1

well, when you simplify each of the equations in the answer choices....which one gives you z < -4?

lets look



z – 4 < 0
+4 +4
z < 4 not correct

z + 3 < 1
-3 -3
z < 2 not correct

z – 3 < 1
+3 +3
z < 4 not correct

z + 4 < 0
-4 -4

z < -4 correct

see what I did?
