Point A is at (-7,-7) and point M is at (-6,-1). Point M is the midpoint of point A and B. What are the coordinates of point B?

The coordinates of point B are (-5, 5).

Given that,

Point A is at (-7,-7), and points M is at (-6,-1).

Point M is the midpoint of points A and B.

We have to determine,

What are the coordinates of point B?

According to the question,

Point A and point B be the ending point of the line segment.

The midpoint formula of a line segment joining these two points is given as:

Then,

Let the coordinates of point B be (x, y),

Point A is at (-7,-7), and points M is at (-6,-1).

Point M is the midpoint of points A and B.

Therefore,

The coordinates of point B is,

And,

Hence, The coordinates of point B are (-5, 5).

(-5,5)

Step-by-step explanation:

For point (x1,y1) and (x2,y2) on a coordinate plane ,

coordinate of midpoint is given by (x1+x2)/2, (y1+y2)/2

In the problem

point A(-7,-7)

let point B be (x,y) thus

midpoint point M for AB will be (-7+x)/2, (-7+y)/2

It is given that M is(-6,-1)

hence  (-7+x)/2, (-7+y)/2 will be same as (-6,-1)

Thus,

(-7+x)/2 = -6            and  (-7+y)/2 = -1

=> -7+x = -6*2                =>  -7+y = -1*2

=> -7+x = -12                  => -7+y = -2

=> x = -12+7                   => y = -2+7

=> x = -5                        => y = 5

Thus, coordinates of point B is (x,y) = (-5,5)

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
