Fit Fast: a set feet per class => y = Ax
Stepping Up: a monthly fee plus an additioal fee per class => h = Bx + C
You can discard the second and the fourth systems because they do not have the form established from the statement.
The first system produce an obvious result given that is represents an option that is always better than the other 5.5x will be lower than 7.5x + 10 for any positive value of x, and so there is no need to make any comparission.
The third system is
y = 7.5x and y = 5.5x + 10 which need to be solved to determine when one rate is more convenient than the other.
Answer: y = 7.5x and y = 5..5x + 10

Answer:
576
Step-by-step explanation:
1. 800*0.8=640
2. 640*0.9=576
<em><u>Solution:</u></em>
Given that we have to multiply the polynomials
Multiplying polynomials is similar to multiplying numbers
When you multiply two terms together you must multiply the coefficient (numbers) and add the exponents
Let us multiply the given polynomials
Multiply each term in first bracket with each term in second bracket
Add the exponents and multiply the coefficients
Combine the like terms -30x and 48x
Combine the like terms 
Thus the polynomials has been multiplied
