At East High School, there are a total of 1050 students in the freshman and sophomore classes. However, the freshman class has 8

0 more students than the sophomore class. Which system of equations could be used to determine the number of freshmen (f) and sophomores (s) in the school?
Choose all that apply.

1. f + s = 1050
s + 80 = f

2. f - s = 1050
f + s = 80

3. f + s = 1050
f + 80 = s

4. f - s = 1050
s + 80 = f

5. f + s = 1050 f - 80 = s

A pair of equations is shown below:
lesya692 [45]

Answer:

The solution to the pair of equations is x=1,y=2

Step-by-step explanation:

The given equations are:

y=6x-4

y=5x-3

To solve the pair of equations graphically, we need to graph the two equations. Their point of intersection is the solution to the pair of equations.

The functions are in the form;

y=mx+b

where m=6 is the slope and b=-4 is the y-intercept of y=6x-4.

and where m=5 is the slope and b=-3 is the y-intercept of y=5x-3.

The two equations have been graphed in the attachment.

They intersected at (1,2).

The solution to the pair of equations is x=1,y=2
