Answer:
f⁻¹(7) = 1
Step-by-step explanation:
Step 1: Write out function
f(x) = 3x + 4
Step 2: Find f⁻¹(x) (or known as inverse f(x))
y = 3x + 4
x = 3y + 4
-3y + x = 4
-3y = 4 - x
y = -4/3 + x/3
Step 3: Plug in 7 into inverse f(x)
f⁻¹(7) = 7/3 - 4/3
f⁻¹(7) = 3/3
f⁻¹(7) = 1

Answer:
t = 14
Step-by-step explanation:
In an equation, you must keep both sides balanced so if you added 8 from the right side you would have to do the same thing to the left side. Also you want isolate the variable on one side so that its easier to solve ( in this case the variable is t )
6 = t - 8
We should plus 8 to both sides to isolate t on the right side
14 = t therefore
t = 14
