<span>The amount of dissolved oxygen in the Missouri River would decrease if large amounts of chemical waste were dumped into it. It would decrease because the chemical waste would feed on the microorganisms and reduce the amount of oxygen in the river.</span>
Hi. You have to do trial and error with each of the choices to see which of those apply. They are points on the given function y=22x+32 that lie on point (x,y). Just substitute the x-and y values to the function.
a. (10,480) => x = 10, y = 480 y = 480 = 22(10) + 32 480 = 252 (does not apply)
b. (5,142) => x = 5, y = 142 y = 142= 22(5) + 32 142 = 142 (apply)
c. (8,208) => x = 8, y = 208 y = 208 = 22(8) + 32 208 = 208 (apply)
d. (7,154) => x = 7, y = 154 y = 154 = 22(7) + 32 154 = 186 (does not apply)
