Which polynomial function f(x) has a leading coefficient of 1, roots of -5, 3 and 6 with multiplicity 1, and root -2 with multiplicity 3? 1. f(x) = 3(x+2)(x+5)(x-3)(x-6)
2. f(x) = 3(x-2)(x-5)(x+3)(x+6)
3. f(x) = (x+2)(x+2)(x+2)(x+5)(x-3)(x-6)
4. f(x) = (x-2)(x-2)(x-2)(x-5)(x+3)(x+6)

figure c

step-by-step explanation:

hope this .

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

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).
