Vlad1618 [11]

Answer:

<u>The correct answer is D.  x + 5≤ - 4</u>

Step-by-step explanation:

Let's review which inequality has - 12 in its solution set, this way:

A. x + 6 less-than negative 8

-12 + 6 < - 8

-6 < - 8 Not correct

B. x + 4 greater-than-or-equal-to negative 6

- 12 + 4 ≥ - 6

- 8  ≥ - 6 Not correct

C. x minus 3 greater-than negative 10

- 12 - 3 > - 10

<u>- 15 > - 10 Not correct</u>

D. x + 5 less-than-or-equal-to negative 4

- 12 + 5 ≤ - 4

- 7 ≤ - 4 This is correct

<u>The correct answer is D.  x + 5≤ - 4</u>

Use the rules of exponents to simplify the expressions. Place a final answer in fraction form. (-1/2)to the power of 3 *(-1/2) t
Pavlova-9 [17]

Answer:

-1/32

Step-by-step explanation:

we have

(-\frac{1}{2})^{3} )(-\frac{1}{2})^{2})

Remember that

The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents

so

(-\frac{1}{2})^{3} )(-\frac{1}{2})^{2})=(-\frac{1}{2})^{3+2})=(-\frac{1}{2})^{5})=-\frac{1}{32}
