Answer:
the equation is corrent if that what your asking
Step-by-step explanation:
1) 3x - 2y = -16 Subtract 3x from both sides
-2y = -3x - 16 Divide both sides by -2
y =
x + 8
2) 9x - 7y = -7 Subtact 9x from both sides
-7y = -8x - 7 Divide both sides by -7
y =
+ 1
3) x - 3y = 6 Subtract x from both sides
-3y = -x + 6 Divide both sides by -3
y =
- 2

Input the first coordinate of an ordered pair in a relation and output the second coordinate of an ordered pair.
Answer:
D. 70^o - 50^o - 70^o
Step-by-step explanation:
The 3 angles of a triangle add to 180 degrees
A. 30^o - 120^o -30^o = 30+120+30 = 180
B. 40^o - 40^o - 100^o = 40+40+100 = 180
C. 60^o - 60^o - 60^o = 60+60+60 = 180
D. 70^o - 50^o - 70^o = 70+50+70 = 190 not a triangle
