Answer:
The equation
represents the equation of the parabola with focus (-3, 3) and directrix y = 7.
Step-by-step explanation:
To find the equation of the parabola with focus (-3, 3) and directrix y = 7. We start by assuming a general point on the parabola (x, y).
Using the distance formula
, we find that the distance between (x, y) is

and the distance between (x, y) and the directrix y = 7 is
.
On the parabola, these distances are equal so, we solve for y:

The answer is 4 because if u divide both equations by eachother you get 4
Answer:
The coordinates of Y' will be: A'(4, -3)
Step-by-step explanation:
Triangle XYZ with vertices
We have to determine the answer for the image Y' of the point Y(-3, 4) with respect to the line mirror y=x.
We know that when P(x, y) is reflected in y = x, we get P'(y, x)
i.e.
The rule of y=x:
As we are given that Y(-3, 4), so the coordinates of Y' will be:
A(-3, 4) → A'(4, -3)
Therefore, the coordinates of Y' will be: A'(4, -3)
Answer: $42.56
Step-by-step explanation:
Percent discount in department store = 38%
The regular price of suit = $112.
Price taken off the regular price of the suit =
38% of $112
So, 38% of $112
= (38/100) x $112
= 0.38 x $112
= $42.56
(i.e the customer will pay $112 - $42.56 = $69.44 only for the suit)
Thus, the price taken off the regular price of the suit is $42.56
