You can solve it by several ways, but easiest and shortest would be "By Elimination"
So, subtract 2nd equation from 1st,
-2x = 20
x = -10
Substitute it in 2nd equation,
-3(-10) + 9y = -6
30 + 9y = -6
9y = -6 - 30
y = -36/9
y = -4
In short, Your Answer would be: (-10, -4)
Hope this helps!
Answer:
the first did it correct
Step-by-step explanation:
First and foremost that is a quadrilateral, because it is a 4-sided figure. If it was a trapezoid it would have only 1 set of parallel lines. So NOT a trapezoid. It is a parallelogram because parallelograms have 2 pair of parallel lines. It is not a rhombus because a rhombus has 4 equal length sides. So it's not a square either. It is not a rectangle either because rectangles have 4 right angles and this one does not. So your choices are 1 and 3.
