Answer:
B. y = 3
Step-by-step explanation:
to solve the equation, you need to get y by itself. so, you have to add y to both sides, then subtract 3 from both sides. after that, you divide both sides by 2 and there's your answer.
it'll look like this:
y + 3 = -y + 9
2y + 3 = 9
2y = 6
y = 3
Answer:
look it up
Step-by-step explanation:
3x + 2y + y - 3x = 180
3y = 180
y = 180/3
y = 60
3x = y - 3x
Let y = 60
3x = 60 - 3x
3x + 3x = 60
6x = 60
x = 60/6
x = 10
Answer: x = 10, y = 60
Answer:
B
Step-by-step explanation:
It opens downwards, so the parabola is negative. This also means the vertex of the parabola is the highest point, therefore it is a maximum.
