Answer:
282 hr <======= see below
Step-by-step explanation:
Distance / rate = time
2.4 x 10^9 mi / 85 m/hr = 28235294 hr
You must have left the power of 10 off of your speed
probably should be 8.5 x 10^6 perhaps? then answer is 282
<h3>If speed was 8.5 x 10^5
then answer becomes ~ 2820 </h3>
Read some notes on reflection. If it asks to reflect it on the x-axis youre going to reflect it either on the bottom or top plane. If it asks to reflect on y-axis youre going to reflect it on either the left or right plane.
Answer:
it should be B

Answer:
The answer is
<h2>
![( - \frac{13}{2} , \: - 3)](https://tex.z-dn.net/?f=%28%20-%20%20%5Cfrac%7B13%7D%7B2%7D%20%2C%20%5C%3A%20%20-%203%29)
</h2>
Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
<h3>
![M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )](https://tex.z-dn.net/?f=M%20%20%3D%20%28%20%5Cfrac%7Bx1%20%2B%20x2%7D%7B2%7D%20%2C%20%5C%3A%20%20%5Cfrac%7By1%20%2B%20y2%7D%7B2%7D%20%29)
</h3>
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-15,4) (2,-10)
The midpoint is
<h3>
![M = ( \frac{ - 15 + 2}{2} , \: \frac{4 - 10}{2} ) \\ = ( - \frac{13}{2} , \: - \frac{6}{2} )](https://tex.z-dn.net/?f=M%20%3D%20%28%20%5Cfrac%7B%20-%2015%20%2B%202%7D%7B2%7D%20%20%2C%20%5C%3A%20%20%5Cfrac%7B4%20-%2010%7D%7B2%7D%20%20%29%20%5C%5C%20%20%3D%20%28%20-%20%20%5Cfrac%7B13%7D%7B2%7D%20%2C%20%5C%3A%20%20-%20%20%5Cfrac%7B6%7D%7B2%7D%20%29)
</h3>
We have the final answer as
<h3>
![( - \frac{13}{2} , \: - 3)](https://tex.z-dn.net/?f=%28%20-%20%20%5Cfrac%7B13%7D%7B2%7D%20%2C%20%5C%3A%20%20-%203%29)
</h3>
