The variable must be raised to the second power
I think the answer is 500 dollars but idk don't quote me sorry if you get it wrong.
Since the focus is at (0, 2) and directrix is y = -2
point where both of these have the same x-value will be at (0, 2) for the focus and (0, -2) for the directrix.
The vertex will also have the same x-value so it will be (0, y).
y-value is half-way between the y-value of the focus, and the y-value of the directrix at x = 0.
Directrix y-value is -2 at x = 0 and for the focus it's 2 at x = 0.
Halfway between y = -2 and y = 2 is y = 0.
So the vertex of the parabola occurs at (0, 0).
So that's x^2 = 4ay = 4(2)y = 8y.
y = 1/8*x^2
hope it helps
11 blue
2 green
7 brown
total is 20 card
7 out of that 20 are brown
so x out of 100% are brown
7/20=x/100 - cross multiply
700=20x
x=700/20
x=70/2
Answer:
The 1st one is y = 11.
The 2nd one is y = 5.
The 3rd one is v = -5.
The 4th one is y = 9.
Step-by-step explanation:
1) -38 = 7y + 17 - 12y
-38 = -5y + 17
-55 = -5y
11 = y
2) 5y + 6 - 12y = -29
-7y + 6 = -29
-7y = -35
y = 5
3) -12v - 9 + 7v = 26
-5v - 9 = 26
-5v = 35
v = -5
4) -5y + 2(y + 2) = -5
-5y + 4y + 4 = -5
-y + 4 = -5
-y = -9
y = 9
