Question 161979: Help! I have 3 sets of points and don't know how to do this????
Here's the problem: Find the slope of the segment drawn from point C (2,2) to the midpoint of D (4,2) and E (-8,18). I got -2 but I'm not sure if that is correct???
Here's one more I'm having trouble with: If Y is the midpoint of segment UV and UY = 4x-3 and YV =x find UV. I got 5x-3 but again I'm not sure if it's right ???? Please help!

Question 171496: Basal energy requirement. The basal energy requirement B is the number of calories that a person needs to maintain the life process. For a 28 yaer-old female with a height of 160 centimeters and a weight of 45 kilograms(kg), B is 1300 calories. If her weight increases to 50kg, then B is 1365 calories. There is a linear equation that expresses B in therms of her weight w. Find the equation and find the basal energy requirement if her weight is 53.2 kg.

Question 172050: I am so sorry but I am having so much trouble understanding how to figure this out. I am being asked about union and intersections of line and rays and union and intersections of angles. I do not just want the answers I really wnat to understand how to do it. The textbook just does not make it clear to me. I have AD U BC there is a line w/two sided arrow over the AD and a line over BC. The second one BC U CF U FB with a line over all of them without any arrows. The third one is angle HCD intersects(symbol upsidedown U)angle ACF. And the fouth one is angle ICA intersects (symbol is the upsidedown U again) EG-this has a line with the two sided arrrows again.
The line ABCD has two other line crossing it (one at point B and the other at point C)and they intersect to create the top of a triangle above rays BC of line.
I pray this is not too complicated and you can help me anyway. I totally understand if you can't, and I have no money right now to offer any of you but when I do I will make a donation to you. I plan to keep your information so when I can I will contact you. I hope you do not feel like I am just saying this to get help. Honestly.
Again I am not just looking for the answers I need to understand how. Thank you so much in advance.
