Answer:
Step-by-step explanation:
Given the equation
A parabola is the locus of points such that the distance to a point the focus equals the distance to a line the directrix.
is the standard equation for an up-down facing parabola with vertex at (h, k), and a focal length |p|.
so
Parabola is symmetric around the y-axis and so the focus lies a distance\ p from the center (0, 0) along the y-axis.
Therefore,

-27
Step-by-step explanation:
Let x = 6 and y = -3
Answer:
100
Step-by-step explanation:
start with what's in the parenthesis':
8 (9.75 - 3.25) + 12 x 4 = 8 (6.50) + 12 x 4
then take the number outside of the parenthesis' time the number inside of them:
8 (6.50) + 12 x 4 = 52 + 12 x 4
now, take the product of the two number on the right side of the addition sign:
52 + 12 x 4 = 52 + 48
finally, add the final two numbers together:
52 + 48 = 100
