Answer:

the answer is A

Step-by-step explanation:

the reason why is because the car starts at 0mph and as the car increases in speed the line will continue to increase and then the car stays at a constant speed which means the line will not go up or down on the y but will get longer on x because of time. and then the the speed decreases. and the only graph that shows an increase, constant, and decrease is graph A.

WRITE THE EQUATION OF THE PARABOLA with a directrix of y=1 and a focus of (0,-1).
stepan [7]

Answer:

-4y = x², or y = - x²/4, or y = -(1/4)x²

Step-by-step explanation:

Because the focus is beneath the directrix, this vertical parabola opens down.  The general formula is 4py = x².  

Because the distance between focus and directrix is 2 units, p = -1 here.  The negative sign shows that the parabola opens down.

4py = x² becomes 4(-1)y = x², or -4y = x², or y = - x²/4

Otto spent 3/4 of the money he had saved on a new video game. If the video game cost $48, how much money did he have before he b
quester [9]

Answer: $64

Step-by-step explanation:

Given: The part of money he spent =3/4

Let the total money Otto has be 'x'.

Then according to the question, we have

\frac{3}{4}x=48

Multiply 4 on both the sides, we get

3x=48\times4

Divide 3 on both the sides, we get

x=\frac{48\times4}{3}\\\\\Rightarrow\ x=64

Hence, the money he had  before he bought the game = $64
