2 answers:

8 0

This is a horizontal parabola and the coordinates of vertex are ( 0, 0 ).
Also the coordinates of focus are: F ( -3, 0 )
so f = -3 and p = 2 f = 2 * ( - 3 ) = - 6
The formula is:
x² = 2 p y
x² = 2 * ( - 6 ) y = - 12 y
Answer:
The equation of the parabola is:
x² = - 12 y.

Answer:

Step-by-step explanation:

Adam plans to choose a video game from a section of the store where everything is 75% off.

The expression written by him for this situation is d - 0.75d.

Here, the part d represents the sale price before discount and the part 0.75d is the discount amount.

The expression written by Rena is 0.25d.

Here, the part 0.25d is the price after discount. Since 75% is the discount, the rate after disount is 25% and 25% of d is 0.25d.
