Question 241575: A pelican flying in the air over water drops a crab from a height of 30 feet. The distance the crab is from the water as it falls can be represented by the function h(t)=-16t2+30, where t is time, in seconds. To catch the crab as it falls, a gull flies along a path represented by the function g(t)=-8+15. Can the gull catch the crab before the crab hits the water? justify your answer. If so, find the time it is caught and the distance above the water at that time.

Question 241600: How do you solve this type of absolute value equation? It has a number outside the absolute value symbol that would indicate the distributive property, but it isn't matching the answers in the back when I tried that. Here is an example:
3/5 |3x+2| +5 = y
Would you try the 2 solutions, one positive and one negative? But I can't see how to do that when you don't know what x is.
Thanks!

Question 242219: I am supposed to graph and identify the y-intercept, but no matter how hard I try I keep getting it wrong. The equation is x + 3y = 6. I know that you have to add -x to both sides so 3y = -x + 6. The example I have says to divide by 3 and then shows y=-1/3x + 2. How did they get 1/3 if they are dividing by 3. (I know it is probably a dumb question but I am an idiot when it comes to math)If I can just figure where the fraction came from then maybe I can get the rest of it. Can someone please help?
