Answer:

z>4

Step-by-step explanation:

-2z-3<5

add 3 to 5: -2z < 8

divide by -2: z < -4

but since you divided by a negative number, you have to change the way the inequality is facing so the answer is z>-4

E the problem

Lera25 [3.4K]

Answer:

D) (0.59, 3.35)

Step-by-step explanation:

The inequality for the thickness of the metal bars is:

$|x-1.971| \leq1.38$

In order for this inequality to be true, the following conditions must be met:

$x-1.971 \leq1.38\\x-1.971 \geq -1.38$

The range of thickness "x" that fits the inequality is:

$x -1.971 \leq1.38\\x\leq 3.351\\x-1.971 \geq -1.38\\x\geq 0.591\\0.59\leq x\leq 3.35$

Thickness ranges from 0.59 to 3.35 units.
