Question

Two lines, E and F, are represented by the equations given below.

Line E: 5x + 5y = 40
Line F: x + y = 8

Which statement is true about the solution to the set of equations?

It is (40, 8).
It is (8, 40).
There is no solution.
There are infinitely many solutions.

Answer 1

yooooooo wassup

Answer 2

im here XD

Answer 3

wassup lol

Answer 4

thanks lol this is math are you good with math

Answer 5

Um yeah I was the person who helped you all Friday or something with your 9 questions

Answer 6

i know who you are i gave you all those medals lol

Answer 7

x+y=8
-x -x
y= 8-x I set this as y equals so that I can plug it into the other equation

5x+5y=40
5x+5(8-x)=40 We've established that y= 8-x, so you can put 8-x in place of y
5x+40-5x=40 Distribute
0x+40=40 Combine like terms
40=40

There are infinite solutions. These lines are the exact same line. Watch this

x+y=8
5(x) + 5(y) = 5(8)
5x+5y=40
See?

Answer 8

so its C

Answer 9

The reason they have infinite solutions is because they intersect, or touch in a million places.

Answer 10

no it's D

Answer 11

There are infinite solutions

Answer 12

Since they're the same line, they have infinitely many intersections, or solutions
