Answer: 45
Length is how long something is and the triangle shows 45 as the length
Answer:
the answer is D
Step-by-step explanation:
8 HAS TWO YS AND
X CAN NOT HAVE TWO YS
AN INPUT ONLY HAS ONE OUTPUT
Answer:
C
Step-by-step explanation:
From any point (x, y) on the parabola the focus and directrix are equidistant.
Using the distance formula
= | y - 5 |
Squaring both sides
(x - 4)² + (y - 1)² = (y - 5)² ← distribute the factors in y
(x - 4)² + y² - 2y + 1 = y² - 10y + 25 ( subtract y² - 10y + 25 from both sides )
(x - 4)² + 8y - 24 = 0 ( subtract (x - 4)² from both sides )
8y - 24 = - (x - 4)² ← add 24 to both sides )
8y = - (x - 4)² + 24 ( divide both sides by 8 )
y = - (x - 4)² + 3
Hence
f(x) = - (x - 4)² + 3 → C
Answer:
Step-by-step explanation:
you have to add the 2 to both sides
so once you do that you have -6 plus 2
you add that together and get -4
therefore x=-4
