The first step is to find the distance from the given point to each of the two foci as follows:
Distance D1:
(D1)^2 = (9-1)^2 + (0-6)^2 = 100
D1 = 10
Distance D2:
(D2)^2 = (11-1)^2 + (6-6)^2 = 100
D2 = 10
The constant sum is the summation of the two distances as follows:
constant sum = D1 + D2 = 10 + 10 = 20
The correct choice is:
a) 20
Answer:
A'(0, 1), B'(3, 1), C'(3, -1), D'(0, -1)
Step-by-step explanation:
Add (-1, 3) to each of the given points:
A' = A + (-1, 3) = (1-1, -2+3) = (0, 1) . . . . for example
The answer is the last choice since in a function, x values in the coordinates cannot repeat themselves. In the first answer, the x-value 2 has more than one y-value meaning it cannot be a function. In the second answer, the x-value -2 also repeats itself and has more than one y-value, and in the 3rd choice, the x-value 5 also repeats.
Answer:
y = 2x - 1
Step-by-step explanation:
In an equation with the form y = mx + b, the slope is m. Because parallel lines have the same slope, the slope of the other line is also 2. Plug this back into the mx + b form to get y = 2x - 1.
