Answer:

exponent of x is 33

exponent of y is 0

Step-by-step explanation:

you need to combine all powers (exponents) of x, and all exponents of y separately.

remember : x to the power of a divided by x to the power of b is x to the power of (a-b).

when multiplying, the "-" turns into a "+".

so, we have actually for x the exponent calculation :

8 - 14 -(-39) = 8 - 14 + 39 = 33

so, x³³ remains.

and for the y exponents

-26 -(-5) -(-21) = -26 + 5 + 21 = 0

so, all the y expressions eliminate each other and y⁰ remains.

Given:

3b+8\geq 14

To find:

The steps to solving the given inequality.

Solution:

We have,

3b+8\geq 14

Subtract 8 from both sides.

3b+8-8\geq 14-8

3b\geq 6

Divide both sides by 3.

\dfrac{3b}{3}\geq \dfrac{6}{3}

b\geq 2

Two steps are:

1. Subtract 8 from both sides of the inequality.

2. Divide both sides of the inequality by 3.

Therefore, the correct option is A.
