Answer:

D 5

Step-by-step explanation:

3x+2 > 14               10 -x ≤7

Solve the first inequality

Subtract 2 from each side

3x+2-2 >14-2

3x>12

Divide each side by 3

3x/3 >12/3

x >4

Now solve the second inequality

10 -x ≤7

Subtract 10 from each side

10-x-10 ≤7-10

-x≤-3

Divide each side by -1, remembering to flip the inequality

x ≥3

Both of these must be true The only number from the choices that is true for both is 5

Alright! When you have a constant to a power times another constant to a power (ex. [x^3 times x^3] ) you simply add the powers and keep the base [x^6]. When you have a power to a power (ex. [(12^3)^3] ) you multiply the powers and keep the base [12^9]. When you have a constant to a power divided by a constant to a power (ex. [ x^2 divided by x^5] ) you subtract the powers and keep the base. It's hard to see the questions, so I'll leave this here for you to use as a guide.
