B is the midpoint of AC, E is the midpoint of BD. If A(-9,-4), C(-1,6), and E(-4,-3), find the coordinates of D

Vadim26 [7]

Answer:

(-3, -7)

Step-by-step explanation:

Let $(x_{A,}y_{A}),(x_{B},y_{B}),(x_{C,}y_{C}),(x_{D,}y_{D})(x_{E,}y_{E)} \text{be the coordinates of points A, B, C respectively}\\\\$

The midpoint coordinates $(x_{M},y_{M})$ of any two points $(x_{1},y_{1})$ and $(x_{2},y_{2})$ are given by $x_{M}=\frac{(x_{1}+x_{2)}}{2}$ and $y_{M}=\frac{y_{1}+y_{2}}{2}$

Since B is the midpoint of AC

$x_{B}=\frac{(x_{A}+x_{C})}{2}=\frac{(-9+(-1)}{2}=\frac{-9-1}{2}=\frac{-10}{2}=-5$

$y_{B}=\frac{(y_{A}+y_{C})}{2}=\frac{(-4+6)}{2}=\frac{2}{2}=1$

Since E is the midpoint of B and D and we are given the coordinates of E as (-4,-3). it follows that

$x_{E}=\frac{x_{B}+x_{D}}{2} = \frac{-4+x_{D}}{2}$

Therefore

$x_{D}=2x_{E}+4=2(-5)+4=-3$

Similarly

$y_{E}=\frac{y_{B}+y_{D}}{2} = \frac{1+x_{D}}{2}y_{D}=2y_{E}-1=2(-3)-7=-7$

1 16) Line x is parallel to line y. What is the measure of angle 6? HELP PLEEEEEASE

Setler [38]

Answer:

$\angle 6 = 93$

Step-by-step explanation:

$\angle 5 = 87$ by properties of parallel lines

$\angle 5 + \angle 6 = 180$ because they form a straight angle

$87 + \angle 6 = 180\\\\\angle 6 = 180-87\\\\\angle 6 = 180 - 80 - 7\\\\\angle 6 = 100 - 7\\\\\angle 6 = 93 \longleftarrow$

You rode your bike on a 6 and 1/2 mile path. You sister rode on a different path that was 2 and 3/10 miles long. How much farthe

Alex_Xolod [135]

To solve, the first step is to find the LCM (least common denominator). In this scenario, it's ten.

6 5/10 - 2 3/10

From here, do the math. It's easy this time, what's 5 - 3? Two.

Now, subtract two from six. (four)

4 and 2/10

4 and 1/5

There! :)
