F(x) = 3x - 2
f(8) = 3(8) - 2
f(8) = 24 - 2
f(8) = 22
f(-5) = 3(-5) - 2
f(-5) = -15 - 2
f(-5) = -17
f(8) - f(-5) = 22 - (-17)
f(8) - f(-5) = 39
Hope this helped! Good luck! :)

Hello!!
Obviously, there are many possibilities for a real world problem. But, here's one option.
"Jeanette owes her friend, Debbie, a sum of money that is a multiple of 8. During the summer, Jeanette earns 60 dollars by selling cookies at a bake sale. After paying Debbie back for the borrowed sum of money, Jeanette has 28 dollars left. What was the sum of money divided by 8 that Jeanette owed Debbie?"
Hope this helps!! Let me know if you have ANY questions.
Answer:
16
26
48
Step-by-step explanation:
x + y + z = 90
z = x - 10 => x = z + 10
y = 3z
=>
(z+10) + 3z + z = 90
5z + 10 = 90
5z = 80
z = 16
x = z + 10 = 16 + 10 = 26
y = 3z = 3×16 = 48
6.) -4/3x+4=y
7.) y=2
8.) Undefined
