Question

Plz help me!!! I need this answered correctly and with explanation!!!
Solve z/−8 ≥ −0.25

Answer 1

z≥-2

Explanation:

z/-8≥-0.25

In order to get the letter z by its self you have to do the same thing to each side of the greater or equal to symbol.

In order to get the z by its self you need to do the opposite as what is shown so you can get down to just the simpiest form: for example if you are multiplying you would end up deviding on both sides of you sign.

So insted of dividing z by -8 we will multiply -8 to each side and so on... I will write it out to show you:

z/-8≥-0.25

*-8 *-8

z≥-2

Answer 2

z≤2

Explanation:

Step 1: Simplify both sides of the inequality.

−1/8z≥−0.25

Step 2: Multiply both sides by 8/(-1).

(8/−1)*(−18z)≥(8−1)*(−0.25)

z≤2
