x^4 - 2x^3 - 2x^2 + 2x^3 - 4x^2 - 4x + 3x^3 - 6x - 6
then combining like terms....
answer is:

Answer:

Chef Rita can feed 20 people with 55 pancakes.

Step-by-step explanation:

We can solve this problem using equivalent ratios. Since we know that Chef Rita can feed 8 people with 22 pancakes, we can set up the ratio:

$\frac{22pancakes}{8people}=\frac{22}{8}$

To solve how many people she would be able to feed with 55 pancakes, we can set ratios equal to each other and solve for 'x' which is the number of people.

$\frac{22}{8}=\frac{55}{x}$

We can see what factor we multiply 22 by to get 55 and then we multiply the denominator by the same factor to get our equivalent ratio. 55 ÷ 22 = 2.5. So, 8 x 2.5 = 20 people.

If you would have to graph x=7, you probably know that this is a vertical line at, well, x=7.

| x | = 7 is nothing more than two vertical lines, namely x=7 or x=-7, as you already wrote down.

| x | = -8 has no (real) solutions, so there is nothing to graph.
