To find the inverse of any function, switch the x's with y's and vice versa.
The current equation given is 
Switch the 
with 
and switch the with
After doing so, we'll have the following equation:
Now, let's move the variables around so that y is isolated on the left side again.
Subtract both sides by 4y
Subtract both sides by x
Divide both sides by -4
That is the answer.
Have an awesome day!

Answer:
13.5 and 1.5
Step-by-step explanation:
y=7x+3
y=9x
9x=7x+3
2x=3
x=3/2
y=9(3/2)
y=13.5

-t
Step-by-step explanation:
Additive inverse of t:
t*-1 = -t
Answer:
I do
Step-by-step explanation:

Since you have two angles that measure 45 degrees. Those 2 equal 90 degrees altogether. Since a triangle measures 180 degrees, you take 180-90 because you already have 2 angles and are trying to find the last one. Then this makes the last angle 90 degrees.
