The math club is doing a fundraiser to raise money to attend a math competition. The club was told by their advisor to raise $2000, but they decided to raise $4000. The club is selling " I like TT" T-shirts for $10 and "i like TT" sweaters for $20. let x equal the number of T-shirts sold and let y equal the number of sweatshirts sold. Write a linear equation to represent raising $4000.
and
Are the graphs of the equations parallel? How can you tell?

step-by-step explanation:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
