Two solutions, x = + 1, -1

3.5 = -3.5x 3.5 / -3.5 = x x = -1

There is no solution. They are parallel.

They are parallel, they have the same slope. They just have different y-intercepts.
anonymous
  • anonymous
which answer?
anonymous
  • anonymous
The first one
anonymous
  • anonymous
No, if they are parallel the set has infinite solutions.
anonymous

I suggest using geogebra.

Solution means intersecting points.
anonymous
  • anonymous
There are no intersecting points in parallel lines.
anonymous
  • anonymous
Oh, crap. You're right.
anonymous
  • anonymous
this is algebra 1. So no solution?
anonymous
  • anonymous
I'm overthinking the entire thing.
anonymous
  • anonymous
Yes, there is no solution.

A dependent system of equations is a system with __________. the same line parallel lines intersecting lines and lines that have the same equation intersecting lines and lines that have the same slope
anonymous
  • anonymous
Dependent system of equations are the same line.
anonymous
  • anonymous
so A?
anonymous
  • anonymous
Independent system of equations intersect one another, as opposed to dependent. And yes, it's A.

Solve the system of equations. x + 3y = −1 2x + 2y = 6 (−4, 1) (2, −1) (4, −1) (5, −2) @izuru

I previously answered a question similar to this, hold on.
anonymous
  • anonymous
okay :)
anonymous

Like, it's the exact same problem. I couldn't find it but I'll still help you out lol So you can use substitution in this one. Try and isolate x in the first equation.
anonymous
  • anonymous
x+3y=-1 -3y -3y x=-4y
anonymous
  • anonymous
-3y and -1 are not like terms.. So it's just x = -3y -1. Now, plug that isolated x into the second equation. 2x + 2y = 6 2(-3y - 1) + 2y = 6
anonymous
  • anonymous
2(-1)+(-1y)=6
anonymous
  • anonymous
You have to distribute 2*(-3y - 1) before adding +2y.
anonymous
  • anonymous
2*-3y-2
anonymous
  • anonymous
@izuru
anonymous
  • anonymous
The equation turns into -2 -6y + 2y = 6. You multiply 2 by -3y and -1.
anonymous
  • anonymous
okay :)

so B? @izuru

@IrishBoy123 b?

b
anonymous

y = -2. Plug it in with the first equation to figure out the value of x.
anonymous

Its D! @izuru
anonymous
  • anonymous
You're right
