Find the inverse function
y=-5x+20

Step-by-step explanation:

The inverse function is a function that reverse a given function.

You can follow this procedure:

The given equation is

First change the position of the x, because is the variable you need.

Now substract 20 in both sides of the equation:

Do the necesary calculations

Now divide by -5 both sides of the equation to clear X

simplify:

Finally you will get:

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
