1st box:
6x and 8x are being combined.
6x-8x=-2x
2nd box:
-4x and -2x (from the 1st box) are being combined.
-2x+4x=2x
3rd box:
6 and 2 are being combined.
6-2=4
Altogether, we would have 4=2x. With one last division of 4/2, we would get 2=x.

aden’s teacher had 4 boxes of pens that each contained y pens. She took 6 pens out of one of the boxes and told her 17 students to divide the remaining pens equally among themselves. Which expression shows the number of pens each student got?
Answers
Answer:
Jaden’s teacher had 4 boxes of pens that each contained y pens.
Number of boxes of pen = 4
Number of pens per box = y
Total number of pens = 4 x y = 4y
She took 6 pens out of one of the boxes told her 17 students to divide the remaining pens equally among themselves.
Total number of pens left = 4y - 6
Number of students = 17

What is an equation of the line that passes through the points (-3, -2) and (2, -7)
Answers
Answer:
y=x-9
Step-by-step explanation:
There are 2 parts to finding the equation of a line: the slope and the y-intercept. In the equation y=mx+b, m is the slope and b is the y-intercept.
First, let's find the slope. 2-(-3)=5 and -7-(-2)=-5, so the slope is -5/5=-1.
Now we can plug in one of the given points to the equation to find the y intercept:
y=x+b
-7=2+b
b=-9
Now, we have the slope and the y intercept, so we can write the equation.
y=x-9

1), At Texas A&M University, tuition and fees for 4 years cost approximately $36,000. If a student could pay for these college expenses by the month, the student's monthly school bill would be about- A $650 B $700 C $750 D $900
Answers
Answer:
C- $750
Step-by-step explanation:
36,000 = 48b
Since the tuition fees for 4 years equals $36,000, you would first need to solve how many months equals 4 years (48). Divide the total sum of the tuition ($36,000) by the number of months the student would have to pay (48) in order to get $750/mo.

Answer:

slope:
[tex]\sf \dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\sf \dfrac{27-9}{1-0}[/tex]
[tex]\sf 18[/tex]
equation:
y - y₁ = m ( x - x₁)
y - 9 = 18 ( x - 0 )
y = 18x + 9
Answer:
y= [tex]\frac{1}{18}[/tex]x + 9
Step-by-step explanation:
(0,9) , (1,27)
([tex]x_{2}[/tex]-[tex]x_{1}[/tex])÷([tex]y_{2}[/tex]-[tex]y_{1}[/tex]) = slope
[tex]x_{2}[/tex]=1 [tex]x_{1}[/tex]=0 [tex]y_{2}[/tex]=27 [tex]y_{1}[/tex]=9
(1-0)÷(27-9) = 1/18
m = slope = 1/18
y- [tex]y_{1}[/tex] = m (x- [tex]x_{1}[/tex])
y-9= [tex]\frac{1}{18}[/tex] (x-0)
y-9 = [tex]\frac{1}{18}[/tex]x
y= [tex]\frac{1}{18}[/tex]x + 9
