Isosceles triangle: is or can be drawn in different ways
Equilateral triangle: all sides are equal
Scalene triangle:none of its sides are equal in length
{ x + y = 1 * ( - 2 )
2 x + 3y = -4
- 2 x - 2 y = - 2
2 x + 3 y = - 4
_______________
y = - 6
Subsititute y = - 6
<span>
2 x + 3 y = - 4
2 x + 3 * (-6) = -4
2 x - 18 = - 4
2 x = - 4 + 18
2 x = 14
x = 14 / 2
x = 7
The solution to the system of equations are:
x = 7 and y = - 6

Answer:
5c^2 +6c +13
Step-by-step explanation:
so we can see than 5c^2
and 13c - 7c are the same = 6c
and 4 +9 = 13
so answer will 5c^2 +6c +13
Substitute
So, -2x-7 = 3x + 3
+2x. +2x
-7= 5x +3
-5x. -5x
-5x-7= 3
+7. +7
-5x= 10
Divide -5 on both sides and you get x= -2
Then substitute -2 in the first equation
-2(-2)-7
4-7
Y= -3
