Step-by-step explanation:

The perpendicular line has a slope that is the negative reciprocal of the other line's slope. So, in this case, the slope should be 1/3 (it's positive because a negative times a negative is a positive). This gets rid of all of the answers except for the last, I suppose.

Find the inverse function of

Neko [114]

The correct answer is C. m-1(x) = $\frac{x + 5}{5}$

You can find the value of any inverse function by switching the m(x) and the x value. Then you can solve for the new m(x) value. The end result will be your new inverse function. The step-by-step process is below.

m(x) = 5x - 5 ----> Switch m(x) and x

x = 5m(x) - 5 ----> Add 5 to both sides

x + 5 = 5m(x) ----> Divide both sides by 5

$\frac{x + 5}{5}$ = m(x) ----> Change the order for formatting purposes.

m(x) = $\frac{x + 5}{5}$

And this would be your inverse, which matches answer C.

How to solve the above simultaneous equation?

soldier1979 [14.2K]

Answer:

C -2 or 1

Step-by-step explanation:

So from the equation you have x^2-x-1=-2*x+1

x^2-x-1+2*x-1=0

x^2 +x -2 =0

D= 1^2 -4*(-2)= 1+8=9

x = (-1+-3)/2

So x is either (-1+3)/2=2/2=1

or (-1-3)/2=-2
