Given equation : y=ax^2
Taking a to the other side we have, x^2=(1/a)*y
This equation describes a parabola that opens up.
When a is negative, the focus is on the negative y-axis, therefore, the parabola opens down.
The answer is a. down.
Answer:i think that it is multiply by 5 cause 1* -5 = -5
Step-by-step explanation: 5*-5=-25
25*-5=-125
Let the length of the playground be x, then the width is 6 + x.
Area = length * width = x * (6 + x) = 6x + x^2 = 216
Solving the quadratic equation x^2 + 6x - 216 = 0, we have x = 12 or -18
i.e length = 12 and width = 6 + 18 = 18
$1000/$50=20 So the executive would have to keep the second car for more than 20 months to come out ahead.
The answer is C
