10 times 50 is 500
So your answer is 50.
Answer:
C
Step-by-step explanation:
Any point (x, y) on the parabola is equidistant from the focus and the directrix.
Using the distance formula
= | y - 3 | ← square both sides
(x - 3)² + (y - 1)² = (y - 3)² ← expand the y- factors
(x - 3)² + y² - 2y + 1 = y² - 6y + 9 ← subtract y² - 2y + 1 from both sides
(x - 3)² = - 4y + 8 ( subtract 8 from both sides )
(x - 3)² - 8 = - 4y ( divide both sides by - 4 )
- (x - 3)² + 2 = y, that is
y = - (x - 3)² + 2 → C
Answer:
-8x+10
Step-by-step explanation:
6(2x + 3) − 4(5x + 2)
=12x+18-4(5x+2)
=12x+18-20x-8
=-8x+10
I hope this helps!
It is a 4 by 5 because 4 times 5 eguels 20
