The error that Maria did was combining all the factors in the algebraic expression without collecting the like terms to a particular side to solve for the variable (n).
What is an Algebraic expression?Algebraic expression involves solving numbers with variables with the use of arithmetic operations e.g.

Maria Said that:
-4n + 3 + 9n - 4 = 4nIf we ignore the like terms and assume all numbers have a variable (n);
Then, we have:

The equation of a line given two points needs to be found. Samuel claims that slope-intercept form will generate the equation and Helena claims that point-slope form will find the equation. Who is correct? Explain your reason by describing both forms.
I know the answer. Just want to see if its close to anyone elses.
Answer:
The answers below are all right :D
Step-by-step explanation:
My answer: Both are correct because to find the equation u need both the pointslope form and slope intercept form.
Short Answer: Both Samuel and Helena are correct. Both forms result in the same equation. Slope-intercept uses slope and a point to find the y-intercept. Point-slope uses slope and a point to solve for y to form the equation.
Sample Response: Both are correct. Using either form will result in the same equation. The slope-intercept form uses slope and a point to find the y-intercept. Point-slope form uses the slope and a point to solve for y to generate the equation.

Answer: Part A the answer is yes and Part B the answer is no.
Step-by-step explanation:
Part A when you divide 7 by 2 you get 3.5 and if you multiply that number by the rest of the numbers and you get the number beneath the other number.
Part B when you divide 8 by 5 you get 1.6 and if you multiply that number by the rest of the numbers and then you don't get the number beneath the other number.

A company manufactures two types of cabinets, type 1 and type 2. It produces 110 total cabinets each week. Last week, the number of type 2 cabinets produced exceeded twice the number of type 1 cabinets produced by 20. If x is the number of type 1 cabinets produced and y is the number of type 2 cabinets produced, the system of equations that represents this situation is x + y = 110 and y = 2x + 20. The number of type 2 cabinets produced last week is . This number exceeds the number of type 1 cabinets produced during the week by .

I would like to ask anyone if they would mind helping me if they could explain in a way that makes sense, how to find the y-intercept with two points... please help me, google tells me how but my head hurts and it makes no sense TwT ty in advance!!
Answer:
Ok so the two points that are given need to be in the form of y2-y1 over x2-x1, meaning the x value from the second set of points needs to be subtracted from the x value from the first set of points, and it is the same for the y values. Then that gives you the slope. You add the slope to the equation y=mx+b. The slope is m, so you put the slope in the m spot. If the slope were 3, it would look like y=3x+b because it is in the m spot. Then, you can choose any 1 set of points given and plug it into the equation. I am going to use the slope 3 , like the last example, and plug it in with the set of points. Say the point was (5,2), you will plug the x value, which is 10 in the situation, next to the the slope. The slope will then be 3(5). Then you will plug in the y value, which is 2, into the y place. At the end, the equation will look like this: 2=3(5)+b. Then you multiply 3 and 5, which is 15, and subtract 2 and 15 which will give you -13. The answer will then be -13=b. That is the y-intercept.

Step-by-step explanation:
A line passes through the points (–3, –4) and (6, 2).
Answer:
-3
Step-by-step explanation:
The x-intercept is 3, here's why
First, you need to get the slope
y2-y1
--------
x2-x1
You should get 2/3
Next, you need to use y=mx+b
y= 2/3x+b
2= 2/3(6)+b You get 6 and 2 from the coordinates
Once this is worked out you'll get y=2/3x-2
To get the x intercept you need to set y equal to 0
0=2/3x-2
Add 2 to each side
0-2 = 2/3x
Multiply each side by 3/2 to isolate x
-2 *3/2 = 2/3x * 3/2
-3 =x
The x intercept is -3
