Jack and jill are collecting canned foods for the homeless. they hope to collect 10 cans per day to reach their goal. they have already collected 120 cans. if the function for this problem is f(c) = 10t + 120, determine how many cans jack and jill will have collected after 8 days.
a: 180 cans
b: 200 cans
c: 220 cans
d: undefined slope.

B:200 becuase "t" is the variable 10 multiplied by 8 day the days they want to plug into t so 80. 80+120 is 200.

square root

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
