Answer and Step-by-step explanation:

$\frac{5}{x-9}$

The domain is all real numbers except 9 (positive)

This is because we can't have 0 in the denominator, and when x equals 9, then the denominator is 0. Anything divided by 0 is undefined, which is why 9 (in this equation) is not included.

Use the formula A=bh , where A is the area, b is the base length, and h is the height of the parallelogram, to solve this proble

harkovskaia [24]

We know that:

A = 1440
H = 32

So you need to work backwards to find base.

1440 / 32 = 45

We can check our work:

32 x 45 = 1440

B = 45

6. Protein bars come in a 4-pack box or 12-pack

cricket20 [7]

Answer:

The 12 pack has a better value.

Step-by-step explanation:

1. create a ratio table.

you want to know how much the 4 pack would cost if it was a 12 pack.

you can see the ratio table in the picture above.

As you can see, when the 4 pack equals $7.68, making it a 12 pack will equal $23.04.

Then, compare 23.04 to 22.32.

In conclusion, the 12 pack has a better value.

Write the word sentence as an inequality.

garik1379 [7]

Answer:

-5b <= -34

Step-by-step explanation:

The inequality phrase, "at most" is same as "less than or equal to". So the algebraic inequality would be -5b <= -34. To solve for b, divide both sides by -5 and make sure to switch the inequality symbol to >= when dividing or multiplying inequalities by a negative number. So b >= 34 / 5.
