Question

Solve the inequality 2 + 5z > 17 and determine for which of the following value(s) for z the inequality is true. Show your work and calculations. 

z = -10, -4, 3, 6    NEED SERIOUS HELP A$AP

jim_thompson5910 · Answer

2 + 5z > 17

2 + 5(-10) > 17

2 - 50 > 17

-48 > 17

That last inequality is false, so z = -10 does NOT work

Do the same with the other values
