Two hoses are filling a pool. The first hose fills at a rate of x gallons per minute. The second hose fills at a rate of 15 gall
ons per minute less than the first hose. To meet the pool maintenance company's schedule, the pool needs to fill at a combined
rate of at least 10 gallons per minute. The inequality represents the combined rates of the hoses:
1/x+1/x-15 more than or equal to 1/10
Which answer choice includes all solutions to the inequality and identifies which interval(s) contain viable filling rates for the
hoses?
