Answer:
1) (2, 3)
2) (2, -5).
Step-by-step explanation:
2x – y = 1
2x +2y = 10 Subtract to eliminate the 2x:
2x - 2x - y - 2y = 1 - 10
-3y = -9
y = 3.
Plug this into the first equation:
2x - 3 = 1
2x = 4
x = 2.
2)
5x – y =15
x + y = -3 Adding to eliminate y:
5x + x - y + y = 15 + -3
6x = 12
x = 2
Plug this into the first equation:
5(2) - y = 15
-y = 15 - 10 = 5
y = -5.
Answer:
68
Step-by-step explanation:
All sides of a rhombus are equal.
Answer:
x=2
Step-by-step explanation:
2x+4=4x
-2x -2x
4=2x/2x
4/2=x
x=2
Since all three sides are different lengths and angles, that triangle would be considered an Isosceles triangle.
0.0032 is finite because it doesn't go on forever. If that number never ended, it would be infinite. I hope this helps!
