<span>(8,9) m = 0.5
point slope form 
y - y1 = m (x - x1)
so
equation

y - 9 = 0.5(x - 8)

answer
</span>
y - 9 = 0.5(x - 8)

Find the inverse function of m(x) = 5x - 5 A m-1(x) = 5x + 5 B m-1(x) = -5x + 5 C m-1(x) = x+5/5 D m-1(x) = x+5/-5x
bogdanovich [222]
Hi there!

m(x) = 5x - 5
First replace m(x) by y.

y = 5x - 5
To find the inverse function we must switch the places from the variables x and y.

x = 5y - 5
Now we need to isolate the y again to find the formula of the inverse function. First add 5 to both sides.

x + 5 = 5y
Switch sides.

5y = x + 5
And finally divide both sides by 5.

y =  \frac{x + 5}{5}
And therefore we can conclude the following:

m {}^{ - 1} (x) =  \frac{x + 5}{5}
The answer is C.
~ Hope this helps you!

Nsider the following system of equations y=6x^2+1, y=x^2+4
sp2606 [1]

The given equations are y= 6x^2+1 and y=x^2+4

Both the equations equal y so we can make them equal

6x^2+1=x^2+4

To bring x term on one side we subtract x^2 both sides

6x^2-x^2+1=4

5x^2+1=4

To isolate x term we subtract 1 both sides

5x^2=4-1

5x^2=3

Dividing by 5 both sides

X^2=3/5

Taking root of both sides we have:

X=±√⅗

Substituting x value to find y

When x=+√⅗=0.7745

Y= 6x^2+1

Y=6(3/5)+1

Y= 18/5+1

Y=23/5 =4.6

When x= -√⅗=-0.7745

Y= 6(3/5)+1

Y=23/5=4.6

Point of intersections are ( 0.7745,4.6) and (-0.7745,4.6)
