3 0

To answer this question you will find out the total number of cupcakes donated and then calculate the amount of each flavor based on the percentage that is stated.

Here are the steps:

1. 12 x 10 x 12 (12 classes each donating 10 dozen) = 1440

2. 0.55 x 1440 (55% are chocolate) = 792 chocolate

3. 1440 - 792 (the remaining number of cupcakes)=648

4. 1/3(33 1/3%) x 648 = 216 red velvet

5. 1440 - 792 (chocolate) - 216 (red velvet) = 432 vanilla cupcakes

Chocolate-792
Red velvet - 216
Vanilla - 432

For the graph of y = -8 the line is horizontal, which means the slope = 0. A parallel line has the same slope so one equation could be y = 2. A perpendicular line has an opposite slope so since our slope = 0 the opposite of that slope is $-\frac{1}{0}$ which a line that is perpendicular to y = -8 could be x = -3. Also notice that these two lines form a 90 degree angle.
