Answer 1

Answer: C: 4

Step-by-step explanation:

Answer 2

The domain of the function f(x) is: -6 < x ≤ 4, and the value that is in the domain of the function f(x) is 4

How to determine the value in the domain?

The function is given as:

f(x) = 2x + 5,   -6 < x ≤ 0

f(x) = 2x + 3,   0 < x ≤ 4

The above means that the domain of the function f(x) is:

-6 < x ≤ 0 and 0 < x ≤ 4

When combined, we have:

-6 < x ≤ 4

This means that x is greater than -6 but does not exceed 4

Hence, the value that is in the domain of the function f(x) is 4

Answer:

x< -5

Step-by-step explanation:

we must separate the x to solve for x.

divide both sides by -3 because this separates x.

Answer:

Step-by-step explanation:

The answer to the inequality is x<-5

The first blank is "divide -3" on both sides

Answer:

Step-by-step explanation: 37/ 24 =1 13/24 = 1.5416667

The answer would be 1 13/24

You want to do
8 2/3
7 1/8
———
But you have to have the same denominators so you (x) 1/8 by 3 and 2/3 by 8 to get

8 16/24
7 3/24

Then you just subtract 16 and 3 to get 13 and subtract 8 and 7 to get 1 so the answer would be 1 13/24

A salesperson at a jewelry store earns 8% commission each week....

Answers

Answer:

heidi earned $56 in commision.

hyou take the amount the jewerly store made, 700 in this case and divide it by 100, to find what 1% is. so 1% is 7$, multiply that  by 8, since she makes 8% and that ur answer
