Question 116283: Can you help me with these questions? I did not get this out of a book, it was a handout. The question is: Find the x and y intercepts and then graph
x-y=2 , -x+4y=4 and y = -4x -4. I do not fully understand the question.
Any help on this is greatly appreciated. Can you explain it step by step, not leaving anything out , please.
Thankyou
Laurie

Question 116847: 0.8 - 4(X-1) = 0.2 + 3(4-X), I had this one solved the other day and it was correct, but I was told that I did not have it in the right steps according to my project directions. Step 1-“Simplify each side separately. step2-Isolate the variable term on one side,step 3“Isolate the variable (x= a number)and step 4-“Check. Substitute the proposed solution . Can someone please explain this to me ? I don't understand how to show the problem step by step like that.

Question 117161: solve the equation using the -b +/- square root of b squared-4(a)(c)divided by 2a
1. I know the formula I just cannot figure this out.
x squared = 196
Also if you can help with another.
x squared -4x +2 = 0

Question 117306: The following equation can be used to find the area of a trapezoid. Solve for the variable b:
A=1/2h(B+b)
I can't seem to figure this one out. I know that B + b represent the lenght of the trapezoid and there are four possible solutions we were given:
B=2A/h
b=B(A-1/2h)
b=A-Bh
b=(2A/h)-B
It can't be the first one, because I am not looking for B, but for b.
Any help would be greatly appreciated.
