1: 9+13-3= 19
2: 6-3= 3
3: 3(9)= 27
Answer:
y = 1
x = -3
Step-by-step explanation:
9x + 2y = 3
-x - y = -12 (multiply second equation with 9)
9x + 2y = 3
-9x - 9y = - 108 (add these to up)
-7y = -105
y = 15 use this to find x
9x + 2y ➡ 9x + 30 = 3 ➡ 9x = -27 ➡ x = -3
Answer:
B
Step-by-step explanation:
The y-int. is -5 like the equation and the slope is positive
Many ways to do this.
A, Plot the points and connect them, if it is a straight line you won.
B, A linear function has a set slope. You can calculate this and apply to all points. If it works you won.
Answer:
5
Step-by-step explanation:
3(14+x) = 57
42 +3x = 57
3x = 15
x = 5
