Question

Help! Medal + fan!
How many solutions will this system of equations have?
y = -3.5x - 3.5
y = -3.5x + 3.5

Answer 1

0. The lines have the same slope, but a different constant value. So they will logically never touch.

Answer 2

o thank u so much do u think u could help me on another one please

Answer 3

Given the equation 5x + y = 7, which equation below would cause a consistent-independent system?

10x + 2y = 14

-15x - 3y = -6

5x + y = -7

6x + 2y = 7

Answer 4

Answer 5

Well, I'd start by reordering the equations into y = mx + b form.
2y = -10x + 14
-3y = 15x + 6
y = -5x + 7
2y = -6x + 7

Then we divide the value in front of the x term by the value in front of the y term (the slope!).
-5
-5
-5
-3.

Doing the same for the original equation we get -5.
If the slopes are the same that means 1 of 2 things:
1. They're the same equations
2. They're parallel and will never touch

So the last option is right.

Answer 6

thank u sooo much u really helped a lot
