2 PointsIf y(x) = x - 2, which of the following is the inverse of Ax)?
O . F'(x) = 2 - x
O B. f'(x) = x-2
O c. f'(x) = 2x
OD. F'(x) = x+2

Answers

Answer:

D

Step-by-step explanation:

let y = x - 2 and rearrange making x the subject, that is

y = x - 2 ( add 2 to both sides )

y + 2 = x

now change x to f^(-1) (x) and y back to x, thus

f^(-1)(x) = x + 2 → D

2. Refer to the figure below. The interior angles formed by the sides of a quadrilateralhave measures that sum to 360°, what is the value of x?________

Answers

Answer:

Your value of x will be 28°

Step-by-step explanation:

First, we'll need to find the length of the two obtuse angles. To do this, you add them together. 124 + 124 = 248°.

Since we know that the entire interior measure of the figure is 360°, you have to subtract 248 from 360 to find out the measure of the two unknown angles together.

The sum of the two unknown angles is 112°.

Now, you have to divide 112 by 4, since both of the angles multiply x by two.

112 divided by 4 is equal to 28.

This means the value of x is equal to 28°

I'll check this just to be sure. First I'll start with the top two angles:

2 x 28 = 56

56 + 56 = 112

Then I'll add it to the bottom two angles:

248 + 112 = 360°

I hope this answers your question!

A prism will always have an even number of vertices. True False

Answers

A prism can have square, rectangular, pentagonal and other polygon shapes but not the circular shape. A prism will always have an even number of vertices. The given statement is true.

What is a prism?

A prism is defined as a three dimensional solid object in which the two ends are identical. It is the combination of the flat faces, identical bases and equal cross sections. The shape of the prism does not have any curve.

Based on the cross-sections, there are two types of prisms, they are regular prism and irregular prism. In a regular prism the bases of the prism are in the shape of a regular polygon whereas in irregular prism it is in the shape of a irregular polygon.

Every prism has vertices. They have an even number of vertices with a minimum of 6 and there is no maximum.

Thus the given statement is true.

If five notebooks cost 5.25 how much would three notebooks cost

Answers

So what you would do is you take 5.25 and divide it by 3 and get 1.75 and to check that do the opposite just do 1.75 times 3 and see if you get 5.25

The perimeter of a rectangle is 46cm. The length is 13 cm. What is the width?

Answers

1.) 2 sides are already gonna be 13 so you already have 26 is you add up both those sides.  13+13=26
2.)Subtract 26 from 46 to get the sum of both the widths added together.
    46-26=20
3.)Divide 20 by 2 so that you can get the width on one side of the rectangle.              20 / 2 = 10
4.) The width of the rectangle above is 10
                                                I hope this helps :)
46 - 13 - 13 

46 - 13 = 33

33 - 13 = 20

20 divided by 2 sides = 10

10cm will be our answer
