Answer:
is standard equation of hyperbola with vertices at (0, ±9) and foci at (0, ±11).
Step-by-step explanation:
We have given the vertices at (0, ±9) and foci at (0, ±11).
Let (0,±a) = (0,±9) and (0,±c) = (0,±11)
The standard equation of parabola is:
From statement, a = 9
c² = a²+b²
(11)² = (9)²+b²
121-81 = b²
40 = b²
Putting the value of a² and b² in standard equation of parabola, we have
which is the answer.
You have 9n and -7 in total so the answer is 9n-7. You add up all the numbers and then add up the numbers with n attached to them
Answer:
2 and 6, 1 and 5
Step-by-step explanation:
Hey there!
Let us take Michael's score as ' x '
Let us take Kathryn's score as ' y '
Michael - 70 less than twice Kathryn's
x = 2y - 70
y = y
Add them, we get , 425
2y - 70 + y = 425
3y - 70 = 425
3y = 495
y = 495/3
y = 165
Kathryn's score = 165
Michael - 2 ( 165 ) - 70
= 260
Hope it helps!
