Answer:

<h2>Original: M(3.5, 2) L(5.5, 2) K(7,5) J(2,5).</h2><h2>Reflected: M(3.5, -2) L(5.5, -2) K(7,-5) J(2,-5).</h2>

Step-by-step explanation:

The coordinates of the given trapezoid JKLM are

M(3.5, 2) L(5.5, 2) K(7,5) J(2,5).

If we want to reflect the trapezoid JKLM over the x-axis, we just need to change its vertical coordinates for their opposite, that is

M(3.5, -2) L(5.5, -2) K(7,-5) J(2,-5).

There reason of this is because if we need a reflection across x-axis, what changes is vertical coordintes, because the figure must go from I quadrant to IV quadrant where y-valus are negative, and x-values remains positive.

Therefore, the ordered pair of the original figure are:

M(3.5, 2) L(5.5, 2) K(7,5) J(2,5).

The ordered pair of the reflection are:

M(3.5, -2) L(5.5, -2) K(7,-5) J(2,-5).

Answer:

J'(-2,5)

K'(-7,5)

M'(-3.5,2)

L'(5.5,2)

Step-by-step explanation:

Please refer to the image attached to this answer.

Trapezoid JKLM is reflected over the x-axis, what do we notice about the ordered pairs of the original figure and the ordered pairs of its reflection over the x-axis is described below.

Point J , K L and M  , when reflected over x axis , there distance from the y axis remains the same in second quadrant. the x coordinate becomes negative however  the y coordinates remains the same.

The coordinates will be as shown in the image attached.

Over what interval is the function of the graph
Svet_ta [14]

Answer:

1 ≤ x ≤ 6                             Option A

Step-by-step explanation:

When graph is constant it means, value of graph ( y-values)  not to be change different values of x in given interval.

In other words, graph must be parallel to the x axis is known as the constant graph.

A function is a measure of the rate of change of function values with respect to change in input values.

In given graph horizontal line is lie on the interval from x ≥ 1 to x ≤ 6.

So, option A is correct.

Jordan has $40 to spend at the yard sale. He buys 6 books for $2 each. He would like to spend the rest of his money on model car
Deffense [45]

Answer:

He can buy 4 model cars

Step-by-step explanation:

∵ His total money = the cost of books + the cost of model cars

∵ He buys 6 books and the price of each book is $2

∵ The cost of each model car is $7 , let the number of model cars is c

∵ He has $40

∴ 6 × 2 + 7 × c = 40

∴12 + 7c = 40

∴ 7c = 40 - 12 = 28

∴ c = 28/7 = 4

∴ He can buy 4 model cars

Answer:

  • 21 of multiple choice and 17 of short answer questions

Step-by-step explanation:

  • Multiple choice = m
  • Short answer = s

<u>Equations:</u>

  • m + s = 38
  • 2m + 3s = 93

<u>Solve for s by eliminating m. Subtract the double of the first equation from the second one:</u>

  • 2m + 3s - 2(m + s) = 93 - 2(38)
  • 3s - 2s = 93 - 76
  • s = 17

<u>Find the value of m:</u>

  • m = 38 - 17 = 21

Listed below are the highest amounts of net worth (in millions of dollars) of celebrities. The celebrities are Tom Cruise, Will
emmainna [20.7K]

<u><em>The range's difference is the highest and lowest value of the data</em></u>

<u><em>RANGE= 250-150= 100</em></u>

<u><em>The mean would be the sum of all values divided by how many values </em></u>

<u><em>250+200+185+165+160+150+150+150+150 / 10 = 1720/10 = 172</em></u>

<u><em>The variance is the sum of squared deviations </em></u>

<u><em>*n=10 </em></u>

<u><em>s^2 = (250-172)^2+(150-172)^2 / 10-1</em></u>

<u><em>which equals an esitmate of 1034.4444 </em></u>

<u><em>take the square root and you get your final answer of 32.1628</em></u>

<u><em>The measure of the variation isn't typical for all celebs, since the numbers are only based on ten highest networths </em></u>
