Which equation represents the situation below. A swimming pool has 320 liters of water in it. Is has a leak and is loosing 2 liters a minute. What equation shows t(x) the total amount of water in the pool with x the amount of time in mintues?

c(x) = -2x+320

c(x) = 320x -2

c(x) = 2x-320

c(x) = 2x+320

Given f(x) = 17-x^2what is the average rate of change in f(x) over the interval [1, 5]?

What else equals 42 and 30 for multiply

Paula makes stained-glass windows and sells them to boutique stores. if her costs total $12,000 per year plus $4 per window for the frame. how many windows must she produce to earn a profit of at least $48,000 in one year if she sells the windows for $28 each? 1. define a variable for the situation. 2. write an inequality that represents her profit. note: revenue is money coming in. cost is money going out. profit is the difference between the revenue and the cost. in other words: revenue - costs profit 3.using words, describe how many windows she must sell to have a profit of at least $48,000.
