Are -9 and 22 like terms

Using the 3 given means, we can see that the mean of the first and last digits is 25, so the correct option is b.

We have 4 numbers:

a, b, c, d.

We know that:

And we want to get

(a + d)/2

We can write this as:

(a + b)/2 - (b + c)/2 + (c + d)/2 = 21 - 26 + 30 = 25

The correct option is b.

Answer:

[tex]x=114[/tex]

Step-by-step explanation:

Since we know that a straight line is 180°, and we know that one of the angles is 66°, we can write a simple equation to figure this out: [tex]x+66=180[/tex] Then, to solve the equation all you would need to do is subtract [tex]66[/tex] from both sides to get [tex]x=114[/tex].

The material needed for the kite is the area of the kite

The amount of material needed for the entire kite is 48 square inches

The given parameters:

KI =6 inches

ET = 8 inches

KT=10 inches

Area of ΔKIT = 17 square inches

Start by calculating the area of the bottom triangle using:

Area = 0.5 * Base * Height

So, we have:

Area = 0.5 * KI * KT

This gives

Area = 0.5 * 6 * 10

Area = 30

The amount of material used is then calculated as:

Material = Area of the bottom triangle + Area of ΔKIT

This gives

Material = 30 + 17

Material = 47

This is approximately 48

Hence, 48 square inches of material is used for the entire kite

but I dont know how to get the inequality sorry

I hoped this helped a little

Step-by-step explanation:

Fisrt you will need to find the average of the numbers by adding them up and dividing by 3 ( because there are 3 numbers )

which would give you 81

then you have to get at least above an 81 to make it go higher but you may have to do a little more than that there for 90 is what you need

Answer:

Step-by-step explanation:

The diagonal of a square is √2 times the side length.

For BD = 4, AD = 4/√2 and AE is half that, or 2/√2 = √2.

  The length of AE is √2.

__

The area of the square is the square of the side length:

  Area = AE² = (2√2)² = 8

_____

Additional comment

The area of a quadrilateral in which the diagonals are perpendicular is found to be half the product of the diagonal lengths. Here, that would be ...

Answer:

your x point is 2

Then, to help you for y=2x just make a table of values

So for y=2(1) y=2, y=2(2) y=4, y= 2(3) y=6

So theres 3 points to start which gives you a hint that each point goes up two times. (0,0) (1,2) (2,4) (3,6)

From the picture attached you can the y intercept is (2,4)

Answer:

Step-by-step explanation:

Use distributive property:a*(b +c) = (a*b) + (a*c)

3(2x + 1) + 7 = 6x - 3 - 2(2-4x)

3*2x + 3*1 +7 = 6x - 3x -2*2 + (-2)*(-4x)

6x + 3 + 7     = 6x - 3 - 4 + 8x

6x + 10          = 14x - 7

6x - 14x         = - 7 - 10

           -8x    = -17

              x    = -17/-8

x = 17/8

Answer:

[tex]f^{-1}(x)=\sqrt{x+1}-3[/tex]

Step-by-step explanation:

We have the function:

[tex]f(x)=y=x^2+6x+8[/tex] with the domain restriction [tex]\{x\geq -3\}[/tex].

And we want to find the inverse of our function.

To find the inverse of our function, we take the following steps:

Therefore, our inverse will be:

[tex]x=y^2+6y+8[/tex]

First, let's subtract 8 from both sides. So:

[tex]x-8=y^2+6y[/tex]

To solve for y, we can complete the square. To complete the square, we:

Our b term is 6. [tex]6/2=3[/tex], and [tex]3^2=9[/tex]. So, we will add 9 to both sides. This yields:

[tex](x-8)+9=(y^2+6y+9)[/tex]

Simplify the left. Complete the square on the right. So:

[tex]x+1=(y+3)^2[/tex]

Take the square root of both sides and solve for y:

[tex]y+3=\sqrt{x+1}\Rightarrow y=\sqrt{x+1}-3[/tex]

Subtract 3 from both sides. So, our inverse is:

[tex]f^{-1}(x)=\sqrt{x+1}-3[/tex]

Part 2)

See below for graph.

Here is also a good time to reinforce the idea of inverses. Notice that the domain of our original function f(x) is [tex]x\geq-3[/tex]. So, this means that the range of f(x) is (looking at the graph) is [tex]y\geq-1[/tex].

When we find the inverse, we will flip the domain and range. Therefore, the domain of our inverse function will be the range of our original function, and the range of our inverse function will be the domain of our original function.

From the graph, we can see that f⁻¹(x) has a domain of [tex]x\geq-1[/tex] and a range of [tex]y\geq -3[/tex]. Therefore, their domain and range are indeed opposites.

And we're done!

Answer:

No.

Step-by-step explanation:

Given the following question:

[tex]7.6, 2.5, 2.2[/tex]

In order for any given sides to form a triangle it has to pass the triangle inequality theorem, which is the sum of any two given sides of the triangle has to be greater than the third side in order for it to be a triangle.

In this case...
[tex]7.6, 2.5, 2.2[/tex]
[tex]7.6 + 2.5 = 10.1[/tex]
[tex]10.1 > 2.2[/tex]

[tex]2.5+2.2=4.7[/tex]
[tex]4.7 < 7.6[/tex]

[tex]7.6 +2.2=9.8[/tex]
[tex]9.8 > 7.8[/tex]

Therefore, your answer is "no" the following sides do not form a triangle.

Answer: Choice D)

6 unit cubes and 18 smaller cubes of volume 1/27 cubic inches

=========================================================

Explanation:

Block A = unit cube that has side length of 1 inch

Block B = cube that has side length 1/3 inch

Block B has a volume of (1/3)*(1/3)*(1/3) = 1/27 cubic inches

If we have 180 of block B, then

180*(1/27) = 180/27 = 6.6667 approximately

The first 6 before the decimal point tells us we have 6 block A's. This is the same as saying that we have 6 cubic inches so far.

The 0.6667 at the end means we have 0.6667*27 = 18.0009 = 18 block B's

So we have 6 unit cubes (block A) and 18 smaller cubes (block B) that have a volume of 1/27 cubic inches

--------------

Another way to look at it

180/27 = (162+18)/27

180/27 = 162/27+18/27

180/27 = 6+18/27

180/27 = 6 remainder 18

The last line can also be found through using long division.

The 6 refers to 6 unit cubes and the remainder 18 is the left over 18 smaller blocks.
