Answer: A

Step-by-step explanation:

This is because...

1st. Simplify both sides of the equation (distribute the 4 and combine like terms)

6 + -x = 20 + 4x + -4 (distributed 4)

-x + 6 = 4x + 16 (combined like terms)

2nd. Subtract 4x from both sides.

3rd. Subtract 6 from both sides.

4th. Divide both sides by -5.

Answer:

a) -3

b) 9

c) -3

Step-by-step explanation:

a)

2^5 * 2^{-8} = 2^a

In cases where we have a multiplication with exponents we keep the integer as it is and we <u>add</u> the exponents. 5 + -8 = -3. Therefore a is 3.

b)

\frac{4^7}{4^-{2}} = 4^b

In cases when we have a division with exponents we keep the integers as it is and we <u>subtract</u> the exponents. 7 - (-2) = 7 + 2 = 9. Therefore, b is 9

c)

\frac{7^9}{7^c} = 7^{12}

We are dividing again however we are finding the denominator.

9 - (c) = 12

Subtract from both sides: -c = 3, To make c positive we just make the value negative, c = -3. Therefore c is -3
