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
I believe it’s a but I’m not exactly sure
Answer:
<u>1</u> would be your y axis
Step-by-step explanation:
1. so the y axis is up and down
2. the x axis is horizontal side to side
3. the x axis is 0
4. the y axis is positive 1
5. So your anwser would be in the format (x,y)
6. It is (0,<u>1</u>)
7. It is positive
8. Plz name me brainliest I would really appreciate it if you need more help just ask me
Thank You
Answer:
240
Step-by-step explanation:
remember that to get from positive to negative you have to go from positive to 0 then to negative .
however the easiest way of solving this is
add both the values , ignore the sign
130 + 110
the difference in the temperature is :
= 240 degrees
Answer:
Step-by-step explanation:
x=√3, y= 3
