Answer:
The answer to your question is: (4, -1)
Step-by-step explanation:
M = midpoint (-1, 1)
A = (-6, 3)
B = (x, y)

x = 2xm - x1
x = 2(-1) + 6
x = -2 + 6
x = 4

y = 2ym - y1
y = 2(1) - 3
y = 2 - 3
y = -1
Answer:
-7 OR -9
Step-by-step explanation:
8-7 in the inside
Absolute value of 1 is 1
OR
8-9 in the inside for -1
Absolute value of -1 is 1
Absolute value signs makes everything positive
Answer: The equation of the parabola is
.
Explanation:
It is given that the focus of the parabola is (-5,-5) and the directrix is y=7.
The standard form of the parabola is,

Where y=k-p is directrix and (h,k+p) is the focus.
Since focus is given,

On comparing,

.... (1)
The directrix is y=7.
.... (2)
Add equation (1) and (2),


Put this value in (1).

Put p= -6, h= -5 and k=1 in the standard form of the parabola.


Therefore, the equation of parabola is
.
Answer: 1 1/4feet
Step-by-step explanation:
From the question, we are informed that the depth of the water in the pool changes by −3/4 foot every hour and that the depth of the water was 5 feet when she started draining.
The depth of the water after 5 hours will be:
= 5 - 3/4(5)
= 5 - 15/4
= 5 - 3 3/4
= 1 1/4 feet
