Answer:

C. 2mn and mn^2

Step-by-step explanation:

All of the other options are like terms.

Option A: -x+3x=2x

Option B: 4a+7a=11a

Option D. 3p^2q+(-p^2q)=2p^2q

Option C: These terms are not like terms since 2mn is not squared while mn^2 is squared.

Hence,

the correct option would be C.

Hope this helps!!! PLZ MARK BRAINLIEST!!!

Answer:

The thrid option or 2mn and mn^2

Step-by-step explanation:

Like terms are sets of terms that have the same variables and powers. All these answer choices have the same variables but answer c are not like terms because the second term is raised to the power of 2 and the first is not. Coefficients do not matter for like terms.

How do I draw and determine the equation of a trend line on a scatterplot
Nat2105 [25]

Step-by-step explanation:

Step 1: Draw your trend line.

You begin by drawing your trend line. You want your trend line to follow your data. You want to have roughly half your data above the line and the other half below the line, like this:

trend line equation

Step 2: Locate two points on the line.

Your next step is to locate two points on the trend line. Look carefully at your trend line and look for two easy to figure out points on the line. Ideally, these are points where the trend line crosses a clearly identifiable location.

For the trend line that we just drew, we can see these two easily identifiable points.

trend line equation

We can easily identify these two points as (3, 3) and (12, 6).

Step 3: Plug these two points into the formula for slope.

The formula for slope is this one:

trend line equation

We can label our first point as (x1,y1), and our second point as (x2,y2). So our x1 is 3, our y1 is 3, our x2 is 12, and our y2 is 6. Plugging these values into the equation for slope and evaluating, we get this:

trend line equation

So our slope is 1/3.

23j-21g+20e-13+52e-37j+45-49e<br> (Like terms)
eduard

The solution to the algebraic expression is: 23e - 21g - 14j + 32

What are algebraic expressions?

Algebraic expressions are mathematical expressions that contain variables, coefficients, and arithmetic operations such as addition, subtraction, division, and multiplication.

Solving algebraic expressions are an important part of mathematics as it helps to improve the aptitude and solving skills of the students.

From the given information, we have;

23j - 21g + 20e - 13 + 52e - 37j + 45 - 49e

let's rearrange by taking the like terms to the same sides;

= 23j -37j - 21g + 20e + 52e - 49e - 13 + 45

= -14j - 21g + 23e + 32

= 23e - 21g - 14j + 32

Therefore, we can conclude that the solution to the algebraic expression is: 23e - 21g - 14j + 32

2x + 3y = -6<br> -2x + 3y = 6<br><br> How do I graph it
Elanso [62]

Answer:

(-3, 0)

Step-by-step explanation:

\:  \:  \: 2x + 3y =  - 6 \\ -2x + 3y =  \:  \:  \: 6   \\   \frac{ +  \:  \:  \:  \:  \:  \:  -   \:  \:  \:  \:  \:  \: =  - }{ }{}  \\  \:  \:  \:   4x \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   =  - 12 \\ \\  x =  \frac{ - 12}{4}  \\  \\ x =  - 3

now,

-2( - 3) + 3y = 6 \\  6 + 3y = 6 \\ 3y = 6 - 6 \\ 3y = 0 \\ y =  \frac{0}{ 3}  \\ y = 0

thus, (-3, 0)
