<em><u>Answer:</u></em>
The answer is: a = -2.
<em><u>Step-by-step explanation:</u></em>
A = -2, because after graphing the equation in Desmos and plugging in various values for a, I found that when a = -2, the equation passed through the point (-3,12), so that's the answer. I'll attach a photo of the graph.

Answer:
If she wants at least one comedy, there are 1484 different combinations.
Step-by-step explanation:
The order in which she wants to pick the movies is not important. So, we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

In this question:
She wants combinations of 3 movies, with at least one comedy. The easiest way to find this is finding the total number of combinations of 3 movies, from the set of 25(18 children's and 7 comedies), and subtract by the total number without comedies(which is 3 from a set of 25). So
Total:
3 from a set of 25.

Without comedies:
3 from a set of 18.

At least one comedy:

If she wants at least one comedy, there are 1484 different combinations.
Answer:
4
Step-by-step explanation:

Do PEMDAS:
Solve The Numbers in the Grouping Symbols. Do the exponents first, and then add and subtract from left to right.

Divide by 24:

The answer would be 4.
Answer:
The number is 2
Step-by-step explanation:
Twice a number (z) = 2*z = 2z
Twice a number (z) added to 21 = 2z + 21
9 times the number added to 7 = 9z + 7
9z + 7 = 2z + 21
Subtract 2z form both sides
9z - 2z + 7 = 21
7z + 7 = 21
Subtract 7 from both sides
7z = 21 - 7
7z = 14
Divide both sides by 7
z = 14/7
z = 2
