Answer:

-9 3/4a+10 2/5

Step-by-step explanation:

-12 * 5/6a = -10a

-12 * -7/8 = 10 1/2

1/14 * 3 1/2a = 1/4 a

1/14 * -1 2/5 = -1/10

Put it together: -10a + 10 1/2 + 1/4a - 1/10

-10a+1/4a = -9 3/4a

10 1/2-1/10= 10 2/5

-9 3/4a + 10 2/5

Find the midpoint of the line segment joining the points (10,7) and (negative 2,negative 7).

Basile [38]

The midpoint of the line segment joining the points (10,7) and (negative 2,negative 7) is (4, 0)

<h3><u>Solution:</u></h3>

Given that line segment joining the points (10,7) and (negative 2, negative 7)

Thus the two points are (10, 7) and (-2, -7)

The midpoint of two points $(x_1, y_1)$ and $(x_2, y_2)$ is given as:

$M(x, y)=\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)$

$\text {Here } x_{1}=10 \text { and } y_{1}=7 \text { and } x_{2}=-2 \text { and } y_{2}=-7$

Substituting the values in formula, we get

$\begin{array}{l}{M(x, y)=\left(\frac{10+(-2)}{2}, \frac{7+(-7)}{2}\right)} \\\\ {M(x, y)=\left(\frac{10-2}{2}, \frac{7-7}{2}\right)} \\\\ {M(x, y)=(4,0)}\end{array}$

Thus the midpoint of line segment is (4, 0)
