h(x) is replaced as h(2). Go to 2 on the x-axis, and go up until you hit the point, which is 0. It can't be 3, because the open point would be anything greater than 3 or x has to be greater than 3. The closed point represents that the y value can work for that piece of the function. Hope this helps!

(20)(0.25) = 15
removing 15 gallons reduces the tank from 20 to 5.
Acamper leaves camp on a kayak and travels 50 miles east on a river, then he ties his kayak to the bank and travels 20 miles north on a bicycle. this trip can be plotted on the coordinate plane, where the camp is the point (0, 0). the distant of the camper to the camp can be found using the distance formula. which other formula can he use? a) 502 - 202 b) 502 + 202 c) 502 - 202 d) 502 + 202
