Output 11q-8:

PLEASE HELP IM STRUGGLING SO BAD AT MATH please help :((

Answers

Step-by-step explanation:

1.

Plug in the values for 48-4t

t= 0

48-4(0) = 48-0 = 48

t=2

48-4(2) = 48-8=40

t=4

48-4(4) = 48-16 = 32

t= 6

48-4(6) = 48-24 =24

t=8

48-4(8) = 48-32 = 16

48 40 32 24 16 is our answer

To find when the output is 0, that means that 48-4t must be equal to 0, so

48-4t=0

subtract 4t from both sides

48=4t

divide both sides by 4

12=t

2.

q=1

11(1)-8 =3

q=2

11(2)-8=14

q=3

11(3)-8 = 25

q=4

11(4)-8 = 36

q=5

11(5)-8 = 47
