The midpoint of AB is M(7. – 7). If the coordinates of A are (8,-6), what are the

IRISSAK [1]

Answer: B = (6,-8)

Step-by-step explanation:

first the midpoint formula is $(\frac{x1+x2}{2},\frac{y1+y2}{2})$

then you take the x co-ordinate of A and substitute it into one of the x values in the first part of the formula:

$\frac{8+x}{2}=7$

then solve it like an equation:

$8+ x=14\\x=6$

then you take the y co-ordinate of A and substitute it into one of the y values in the second part of the midpoint formula:

$\frac{-6+y}{2} =-7$

then solve it like an equation:

$-6+y=-14\\y=-8$

∴ the answer is x=6, y= -8

which is expressed as a point, B(6,-8)

Help? Thanks!!!!!!!! If possible show work please!

Answer:

$B =102$

$Y = 32$

Step-by-step explanation:

Solving (47):

To solve for B, we have:

$B + 50 + 28 = 180$ --- sum of angles in a triangle

This gives

$B + 78 = 180$

Collect like terms

$B =- 78 + 180$

$B =102$

Solving (48):

To solve for Y, we have:

$X + Y+ Z = 180$ --- sum of angles in a triangle

This gives

$Y = 180 - X - Z$

Where

$W+ X=180$ -- angle on a straight line

Solve for X

$X=180 -W$

$X=180 -100 = 80$

So, we have:

$Y = 180 - X - Z$

$Y = 180 - 80 - 68$

$Y = 32$

Answer:

$P(Green\ and\ Green) = \frac{25}{144}$

Step-by-step explanation:

Given

$Green=5$

$Blue = 7$

Required

$P(Green\ and\ Green)$

This is calculated as:

$P(Green\ and\ Green) = P(Green) * P(Green)$

Since, it is a probability with replacement, we have:

$P(Green\ and\ Green) = \frac{Green}{Total} * \frac{Green}{Total}$

So, we have:

$P(Green\ and\ Green) = \frac{5}{12} * \frac{5}{12}$

$P(Green\ and\ Green) = \frac{25}{144}$

The coordinate of point V is at (-16, 9)

If Point T(-9,5) lies on the perpendicular bisector of UV, this means that the point divides the line UV into two equal parts

Given the following coordinates

Midpoint T = (-9, 5)

U = (-2, 1)

Required

coordinate of point V

Using the midpoint formulas;

$T(x, y) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}) \\T(-9, 5) = (\frac{-2+x_2}{2}, \frac{1+y_2}{2})$

Get the value if x₂ and y₂

$-9 = \frac{-2+x_2}{2}\\-18 = -2+x_2\\x_2 = -18+2\\x_2 = -16\\$

Similarly;

$5 = \frac{1+y_2}{2}\\10 = 1+y_2\\y_2 = 10-1\\y_2 = 9\\$

Hence the coordinate of point V is at (-16, 9)
