Question

Can anyone help me solve this function please?

Answer 1

the answer is -5

Explanation:

F(t)=-3(t)+4

it told you that F(t) is equal to 19

so -3*-5=15+4=19

Answer 2

f(-5) = 19

Explanation:

f(t) = -3t+4

Let f(t) = 19

19 = -3t+4

Subtract 4 from each side

19 - 4 =-3t+4-4

15 = -3t

Divide each side by -3

15/-3 = -3t/-3

-5 = t
