Given :

Ben shared his post with two friends. Each of those friends shares with 3 more everyday, so the number of shares triples each day.

Exponential equation of the form

The number of shares triples each day

So the value of b is 3

Now we find out the value of 'a'. use the given table . Lets pick (0,2) from the table

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

the answer is 1/4
