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:

Answer:
x (x^2+4)
Step-by-step explanation:

Answer:
The answer is 1/4
Step-by-step explanation:
When you split something into fourths, you each get 1/4 of it.
Answer:
y = -x + 3
Step-by-step explanation:
Find the slope using the formula [ y2-y1/x2-x1 ]. We can use the points (0, 3) and (3, 0) to solve.
0-3/3-0
-3/3
-1
From the graph, the y-intercept is (0, 3). Input all the data we know into the slope intercept form expression [ y = mx + b ].
y = -x + 3
Best of Luck!
