Answer:
x= 1
y= -1
Step-by-step explanation:
y=-2x+1
2x-2y=4
substitute for y
2x-2(-2x+1)=4
reduce
2x+4x-2=4
6x=6
x=1
y= -2(1)+1
y= -1
The angles will help you tell the difference. In a rectangle, all angles are 90 degrees. In a rhombus, the 2 opposite facing angles are the same and all side lengths are the same.
Hope I helped. :P
Answer:
x = 4
Step-by-step explanation:
Well, while this is not a full quadratic equation, this can still be worked with, so let's get started.
Taking , we can simplify this just to make it a bit more professional, to say (We can do this because of the Symmetric Property of Equality, which states that a=b then b=a).
Now, we can really start by dividing both sides by 6, to get , and then divide both sides by x to get .
So, the answer of this quadratic equation is x = 4.
