Given f(x) = x² + x + k, and the remainder when f(x) is divided by x-9 is 70, then what is the value of k?

Step-by-step explanation:

According to the Remainder Theorem if you divide any polynomial, , by , the remainder is .

If you want to have a remainder of when we divide it by , we are essentially solving for

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
