In addition to writing new facts for February 29, the twins also need to add another image in the middle of their flip-book animation. The animation sequence is of Dorothy's house from the Wizard of Oz as it is being carried over the rainbow by a tornado. The house in the February 28 drawing has been rotated to create the house in the March 1 drawing. Carlos believes that he can get from the February 28 drawing to the March 1 drawing by reflecting the February 28 drawing, and then reflecting it again.

A. What convinces you that the February 29 image is a reflection of the February 28 image about the given line of reflection?

B. What convinces you that the March 1 image is a reflection of the February 29 image about the given line of reflection?

C. What convinces you that the two reflections together complete a rotation between the February 28 and March 1 images?

If the function is translated 4.5 units to the left to createe the graph of function g(x), hence the resuting function will be g(x) = (x + 4.5)^2

Given the function expressed as
f(x) = x^2

If the function is translated 4.5 units to the left to createe the graph of function g(x), hence the resuting function will be:

g(x) = (x + 4.5)^2

Answer:

300 [tex]m^{2}[/tex]

Step-by-step explanation:

The spread has a rate of 25 [tex]m^{2}[/tex] per every 1/6 hour.  That can be expressed as   25 [tex]m^{2}[/tex] per every 1/6 hour:

25 [tex]m^{2}[/tex]/ (1/6 hour), or

You've made your grade level high school, lower it to Grade 4. Thank you!

The correct answer is the inverse matrix: [ 1 -3 2]

                                                                      [ 2 -5 3]

                                                                      [-1 3 -2]

To find the inverse matrix that can be used to solve the given system of equations, we need to represent the system in matrix form as AX = B, where A is the coefficient matrix, X is the column matrix of variables, and B is the column matrix of constants.

The given system of equations can be written as:

[1 -1 -1] [x] [ 4]

[-1 2 3] * [y] = [-2]

[ 1 1 4] [z] [10]

To find the inverse matrix, we'll set up the augmented matrix [A | I], where I represents the identity matrix:

[1 -1 -1 | 1 0 0]

[-1 2 3 | 0 1 0]

[1 1 4 | 0 0 1]

Using Gaussian elimination, we'll perform row operations to transform the left side into the identity matrix, while applying the same operations to the right side. The resulting matrix on the right side will be the inverse matrix.

After performing the row operations, the augmented matrix becomes:

[1 0 0 | 1 -3 2]

[0 1 0 | 2 -5 3]

[0 0 1 | -1 3 -2]

Therefore, the inverse matrix is:

[ 1 -3 2]

[ 2 -5 3]

[-1 3 -2]

Hence, the correct answer is the inverse matrix:

[ 1 -3 2]

[ 2 -5 3]

[-1 3 -2]

Answer:A

Step-by-step explanation:

Because as you look around we notice line A. We can see that when we look at it there is symmetric. The line divide both of the parts equal

Let us set up some variables:

Now let us set up some equations based on the facts:

Equations:

   L = 4W     -- equation 1

   2L + 2W = 80 -- equation 2

   Plug the value of L from equation 1 into equation 2

    2(4W) + 2W = 80

     8W + 2W = 80

        10W = 80

           W = 8 -- equation 3

   Plug the value of W from equation 3 into equation 1:

    L = 4W = 4 * 8 = 32

Therefore the length is 32 and the width is 8.

The cost would be the same for Justin and Bella if 500 checks are sold, costing about $200.

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the equation for Bella:

c = 0.1n + 150

Where C is the monthly cost for n checks.

For Justin:

1.2 = 3k

k = 0.4

C = 0.4n

To have the same cost:

0.1n + 150 = 0.4n

n = 500

c = 0.4(500) = 200

The cost would be the same for Justin and Bella if 500 checks are sold, costing about $200.

Answer:

The midpoint formula

Step-by-step explanation:

(x,y)=(x1+x2)/2,(y1+y2)/2 ..(Take any two points that are opposite to each other in this case first and third points)

(x,y)=(1+2)/2,(-4+9)/2

(x,y)=3/2,5/2

As the diagonals of a square are equal, their intersection point will be the midpoint.

Answer:

x = -1, y = 1

Step-by-step explanation:

x + 2y = 1

Subtract 2y from both sides

x + 2y - 2y = 1 - 2y (simplify) -> x= 1 - 2y

----

-x + y = 2

Subtract y from both sides

-x + y - y + 2 - y (simplify) -> -x = 2 - y

Divide both sides by -1

[tex]\frac{-x}{-1}[/tex] = [tex]\frac{2}{-1}[/tex] - [tex]\frac{y}{-1}[/tex] (simplify) -> x = -2 + y
