Answer:

y = 2x- 3

Step-by-step explanation:

1) D // D' , this means that mD = mD'

6x -3y +18 =0

6x +18 =3y

6x/3 +18/3 = y

2x +6 = y. m= 2

2) Find the equation of D'

y - y' = m (x - x')

y - 1 = 2(x - 2)

y-1 = 2x - 4

y = 2x-3

PLS HELP<br> If f(x) = x2 -1, what is the equation for f–1(x)?
Anon25 [30]

We have a function,

f(x)=x^2-1

and we are asked to find its inverse function.

An inverse function essentially gets you the original value that was dropped into a function.

For example,

If I put 5 into f(x) I will get 24. Now If I take 24 and put it into the inverse function I have to get number 5 back.

The way to determine the inverse function swap the x and the f(x), then solve for f(x),

x=f(x)^2-1

f(x)^2=x+1

f(x)=\pm\sqrt{x+1}

Of course the notation demands that the obtained function be called,

f^{-1}(x)=\pm\sqrt{x+1}

Hope this helps :)

Sonbull [250]

Answer:

5

Step-by-step explanation:

You need to first add up all the berries: 2+2+5+7+9 which is 25.

There are 5 people so you need to divide 25 by 5: 25÷5 which is 5

So each person will have 5 berries each.

Answer:

center: P

Radius: 12cm

# of radii: 5

Diameter: 24cm

# of diameters: 2

Circumference: 75.36cm

Step-by-step explanation:

the center is labeled with the point p

radius is the distance from the center to the circumference of a circle

diameter is the distance from one point on a circle through the center to another point on the circle. (and twice the radius)

circumference is 2(pi)r

pi can be rounded to 3.14
