The answer is (-21, 13) for The second endpoint.
Let's start by calling the known endpoint L and the unknown K. We'll call the midpoint M. In order to find this, we must first note that to find a midpoint we need to take the average of the endpoints. To do this we add them together and then divide by 2. So, using that, we can write a formula and solve for each part of the k coordinates. We'll start with just x values.
(Kx + Lx)/2 = Mx
(Kx + 1)/2 = -10
Kx + 1 = -20
Kx = -21
And now we do the same thing for y values
(Ky + Ly)/2 = My
(Ky + 7)/2 = 10
Ky + 7 = 20
Ky = 13
This gives us the final point of (-21, 13)
Answer:
The correct option is C) $145,000
Step-by-step explanation:
Consider the provided regression.
sales y in $1000 and advertising x in $100
We have given that they spent $900 in advertising.
That means substitute x=9 in above regression because x is in $100.
It is given that y in $1000.
That means the total sale is 145×$1000=$145000.
Hence, the correct option is C) $145,000

Answer:
16/7
Step-by-step explanation:
If the segments are congruent, their lengths are equal:
(1/2)x -3 = 5 -3x
(3 1/2)x = 8
x = 8/(3.5) = 16/7
The value of x is 16/7.
_____
<em>Comment on the question</em>
This value of x makes the lengths of the segments be -13/7 units. Usually, negative lengths are considered impossible for line segments.
