Given :

A point U located at (1,-4) on the coordinate plane.

To Find :

The reflection of point U on x-axis.

Solution :

Reflection of any point ( h , k ) on x-axis is ( h , - k ) .

So , the reflection of point U i.e ( 1 , -4 ) is ( 1 , 4 ) .

Therefore , the ordered pair describes the location of U' is ( 1 , 4 ).

Hence , this is the required solution .

<u>Answer</u>:

18 clips for $7.38 is the best value deal.

<u>Step-by-step explanation:</u>

An office is restocking office supplies. The table below shows the cost for the number of boxes of paperclips. We need to find what is the best value is.

To find the best value for money we can check the price of each paperclip.

To check the price of each paper clip we can use the following formula:

$\text{Price of each paper clip} =\frac{\text { price of the box }} {{\text {number of clips in the box }}}$

Now we can calculate the best value deal as follows:

$\text{Price of each clip is box 1}=\frac{7.38}{18}=0.41$$

$\text{Price of each clip is box 2}=\frac{15.39}{27}=0.57$$

$\text{Price of each clip is box 3}=\frac{13.50}{30}=0.45$$

$\text{Price of each clip is box 4}=\frac{18.36}{36}=0.51$$

$\text{Price of each clip is box 5}=\frac{18.80}{40}=0.47$$

So, from looking at the prices of each paperclip we can conclude that the 18 clips for $7.38 is the best value deal.

A rectangular picture frame measures 63 cm by 63 cm. What is the perimeter or distance around the picture frame in meters? m

Natalija [7]

Hi!

We need the perimeter in meters, so we have to turn cm into m.
63 cm = 0.63 m

The perimeter is the sum of all side measures:
P = 0.63 + 0.63 + 0.63 + 0.63
P = 4 * 0.63
P = 2.52 m

Alex787 [66]

The data set that has a variation, or mean absolute deviation, similar to the data set in the given dot plot is; Option D

<h3>How to Interpret Dot Plots?</h3>

The given dot plots options are as seen in the attached brainly link.

Now, the sample dot plot shows a total of 10 dots with 3 dots on 52, 2 dots on 53, 1 dots each on 54, 55, 56, 57, 58.

Looking at the options, the only one that represents the variation, or mean absolute deviation of the given sample is Option D.

Y=-3x+9<br> y=-x-5 <br><br> what is the solution for the system of equations?

alexandr402 [8]

Our system of equations is:

y = -3x + 9

y = -x - 5

To solve this system of equations, we are going to use substitution. This means that we are going to substitute the second equation into the first equation since both are already solved for y in terms of x.

y = -3x + 9

-x - 5 = -3x + 9

Now, we must simplify by moving all of the constant terms to one side of the equation and all of the variable terms to the other side.

-x - 5 = -3x + 9

2x - 5 = 9

2x = 14

Finally, to undo the multiplication between the coefficient 2 and the variable x, we must divide both sides by 2 to get the variable x alone.

x = 7

Next, we must substitute in this value we have solved for x into one of the original equations to solve for the other variable, y.

y = -3x + 9

y = -3(7) + 9

To simplify, we must multiply through the parentheses and combine like terms by addition.

y = -21 + 9

y = -12

Therefore, your final answer is x = 7 and y = -12, or as an ordered pair (7, -12).

Hope this helps!
