Let m(x) = x / x−1
allsm [11]

Answer with Step-by-step explanation:

We are given that a function

m(x)=\frac{x}{x-1}

a.We have to find the inverse of m.

Suppose, y=m(x)=\frac{x}{x-1}

yx-y=x

yx-x=y

x(y-1)=y

x=\frac{y}{y-1}

Replace x by y and y by x

y=\frac{x}{x-1}

Substitute y=m^{-1}(x)

g(x)=m^{-1}(x)=\frac{x}{x-1}

b.When the inverse function of given function is \frac{x}{x-1}

Then , we get fog(x)=f(g(x))=\frac{\frac{x}{x-1}}{\frac{x}{x-1}-1}

fog(x)=\frac{x}{x-x+1}=x=I(x)

When f and g are inverse to each other then fog(x)=Identity function.

c.If f(x)=x

It is self inverse function.

Pretty please help me ❤️pleaaaase
never [62]

Answer:

Sue = 25.75

Dave = 29.5

Tom = 19.75

Sue = s

Tom = t

Dave = d

Step-by-step explanation:

s+t+d = 75

s-6=t

d +16 = s+t

d+16+d= 75

2d = 59

d = 29.5

t = s-6

t+s = 45.5

s-6+s= 45.5

2s = 51.5

s= 25.75

t= 19.75

Answer:

-4/5

Step-by-step explanation:

Slope of line = (y2 - y1) / (x2 - x1)

Two points on the line are (2,-3) and (-3,1)

Apply the formula

Slope = (1-(-3)) / (-3-2) = -4/5

A triangle has vertices at L(2, 2), M(4,4), and N(1,6).
mr Goodwill [35]

Answer:

The rule for the transformation is (x, y) (-x, -y).

The coordinates of L'are (-2,-2).

The coordinates of N'are (-1,-6).

Step-by-step explanation:

Given

L = (2,2)

M = (4,4)

N = (1,6)

Ro=180

Required

Select three options

The rule to this is:

(x,y) \to (-x,-y)

So, we have:

L = (2,2)

L' =(-2,-2)

M = (4,4)

M =(-4,-4)

N = (1,6)

N' = (-1,-6)
