Answer:
A
Step-by-step explanation:
For any point (x, y ) on the parabola the focus and directrix are equidistant
Using the distance formula
= | y - 8 |
Squaring both sides gives
(x - 2)² + (y - 4)² = (y - 8)²
(x - 2)² + y² - 8y + 16 = y² - 16y + 64 ( rearrange and simplify )
(x - 2)² = - 8y + 48
8y = - (x - 2)² + 48
y = - 
(x - 2)² + 6 → A
Answer:
no solution
Step-by-step explanation:
If we subtract the left side of the equation, we get ...
This equation will equal zero only if m=3, which is disallowed because it makes the denominator zero. Thus, there is no solution.
Answer:
∠ABE and ∠CBD
∠ABC and ∠EBD
Step-by-step explanation:
we know that
<u>Vertical angle</u>s are a pair of opposite and congruent angles formed by intersecting lines
In this problem we have that
∠ABE=∠CBD ------> by vertical angles
∠ABC=∠EBD ------> by vertical angles
therefore
The angles that are vertical angles are
∠ABE and ∠CBD
∠ABC and ∠EBD
8*4=32
7*4=28
340÷32=10.625
350÷28=12.5
12.5-10.625= 1.875
The third term is 9
t(3)=2(3)+3
6+3 = 9
