Here is how you solve this:

1) If a line bisects an angle, then both angles are equal (This means that angle OLN and angle OLM are equal).

2) If 2 angles of 2 triangles are equal, then the sides opposite of each angle are equal (This means that, since angle OLN and angle OLM are equal, side NO and side OM are equal).

3) If NO=OM, then OM=4.

The answer is x=4.

Karen is investigating if age has any effect on political party preferences. What is the explanatory variable?

anastassius [24]

Using variable concepts, it is found that the explanatory variable is the age.

<h3>Explanatory and response variables:</h3>

The variables of an experiment are divided into explanatory and response.

The response variable is the one that is the focus of the study, that is, the one that can be changed.

The explanatory is the one that explains the reason of the change in the response variable.

In this problem, the <u>age can effect the political party preference</u>, hence:

The variable that is changed is the political party preference, hence it is the response variable.

The reason is the age, hence it is the explanatory variable.

John bought a used truck for $4,500 he made an agreement with the dealer to put 1500 down and make payments of $350 for the next

blsea [12.9K]

So, his down payment was 1500.

He has 3000 to pay off.

Yearly Payment = 350*12 or 4200

Yearly Interest = 3000/Yearly Payment or 71%

I am 100% sure that is right, you sure you didn't make a mistake copying.

A student has earned scores of 87, 81, and 88 on the first 3 of 4 tests. If the student wants an average (arithmetic mean) of ex

Juli2301 [7.4K]

To find an average you take the numbers to be averaged and add them together then You take the number and divide it by the number of numbers, in this case 4, and that gives you the average.
on this problem you want to do the opposite. you know the average she wants, an 87, so you multiply it by 4. 87*4=348. then you add the three numbers you have (88,81 and 87) and you get 256.
then you subtract 256 from 348 and you get 92. 92 is your answer to check just add 87+81+88+92=348
348/4=87
87 was the average she wanted.
Hope this helped! good luck :)

Which graph shows the solution to this system of inequalities?<br><br> Y< 2x+4<br> Y > -x -3

dsp73

Y < 2x + 4.....u have a dashed line with shading below the line....u have a y int of (0,4)...u have an x int of (-2,0) and a slope of 2

y > -x - 3...u have a dashed line with shading above the line....u have a y int of (0,-3) and an x int of (-3,0) and a slope of -1

ur graph is : There is a problem....it will either be the 2nd one or the 3rd one....because one of ur inequalities is written incorrectly...
** IF y > -x - 3 is supposed to have an equal sign in there...then ur answer is the 2nd graph
** IF y < 2x + 4 is supposed to have an equal sign in there...then ur answer is the 3rd graph
