Janelle alternates between running and walking. she begins by walking for the short period, and then runs for the same amount of time. she takes a break before beginning to walk again. consider the four graphs below. which graph best represents the given situation

yes

step-by-step explanation:

faster, im not sure why but i know it is faster

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).

it is impossible.
