Answer:
Yes it is tangent because it is touching a certain point
Step-by-step explanation:
Heres a pic i found of an example and it looks exactly like that one
Answer:
D
Step-by-step explanation:
From any point (x, y) on the parabola the focus and directrix are equidistant
Using the distance formula
= | y + 1 |
Squaring both sides
(x + 5)² + (y - 5)² = (y + 1)^2 , that is
(y + 1)² = (x + 5)² + (y - 5)² ← subtract (y - 5)² from both sides
(y + 1)² - (y - 5)² = (x + 5)² ← expand left side and simplify
y² + 2y + 1 - y² + 10y - 25 = (x + 5)²
12y - 24 = (x + 5)² ← factor left side
12(y - 2) = (x + 5)² ← divide both sides by 12
y - 2 =
(x + 5)² ← add 2 to both sides
y =
(x + 5)² + 2
or
f(x) =
(x + 5)² + 2 → D
Answer: Is this a legitimate question?
Step-by-step explanation:
So because of PEMDAS you want to distribute the 2 to the parentheses so you'll get
6x-19=2x-2+11
Then you can just add like terms
6x-19=2x+9
Now you want to get all your variables on one side so you'd add 19 and subtract 2x
4x=28
Now you divide 28 by 4
x = 7
P square=P triangle equilateral
4(x+2)=3*2x
4x+4*2=6x
4x+8=6x
6x-4x=8
2x=8
x=8/2
x=4
