Kendall and Asa are both saving up money to buy new mountain bikes. Kendall has $50 and will save $10 every week. Asa has $15 and will save $15 every week. After how many weeks will Kendall and Asa have the same amount of money?

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
