Answer: $13
Step-by-step explanation:
Answer:
x =
y²
Step-by-step explanation:
Any point (x, y ) on the parabola is equidistant from the focus and the directrix
Using the distance formula, then
= | x + 3 |
Squaring both sides
(x - 3)² + y² = (x + 3)² ← expanding both sides
x² - 6x + 9 + y² = x² + 6x + 9 ← subtract x² + 6x + 9 from both sides
- 12x + y² = 0 ( subtract y² from both sides )
- 12x = - y² ( divide both sides by - 12 )
x =
y²
Answer:
= 5
Step-by-step explanation:
z - x + y
4 - 2 + 3 = 5
Answer:
The answer would be 26
Step-by-step explanation: (Broken down into 2 parts)
-PART ONE- solving (12-7) x (8-5) -7
(12-7) x (8-5) -7 (do whats in parentheses first)
(5)x (3) -7 (multiply 5x3)
15-7 (subtract)
ANSWER- 8
-PART TWO- solving (16-4) + (10 - 12 divided by 3)
(16-4) + (10 - 12 divided by 3) (do what is in parentheses)
12 + 10-4 (add)
22-4 (subtract)
ANSWER- 18
Now combine the two answers 18+8 and you get 26
Therefore, 26 is the final answer.
Hope this helps!!
