If you would like to solve the system of equations, you can do this using the following steps:
2x + 3y = 40
-2x + 2y = 20
____________
2x + 3y - 2x + 2y = 40 + 20
5y = 60 /5
y = 60/5
y = 12
<span>2x + 3y = 40
</span>2x + 3 * 12 = 40
2x + 36 = 40
2x = 40 - 36
2x = 4
x = 4/2
x = 2
(x, y) = (2, 12)
The correct result would be <span>d. x = 2, y = 12.</span>
-4 =
- 5
- 5 = -4 (Switched sides)
(
- 5)20 = (-4)20 (Multiply both sides by 20)
r-100 = -80
r - 100 + 100 = -80 + 100 (Add 100 to each side)
r = 20Hope this helped :)
Answer:
(-2,0)
Step-by-step explanation:
intercepts at (-2,0) horizontally. look at the graph
Y=x+7
Step-by-step explanation: because your slope is the x value and in the coordinates the y value is 7 and you put it in the form y=Mx+b
