If 1 gallon weighs 8.34 lbs.....then 6 gallons weighs (6 * 8.34) = 50.04 lbs
First you solve the brackets;
68+7 = 75
Then you add the 93;
75+93 = 168
I believe that it should be that the functions intersect at x=2
Answer: 0 slope, horizontal line.
Step-by-step explanation:
when using y2-y1/x2-x1, you would get 8-(-3)/5-5. This simplifies to 11/0, which means that the line would have 0 slope. A line with 0 slope is a horizontal line.
The answer is

. I've demonstrated the 'split and combine' method in the image attached.
This principal is based on the fact that you can multiply and divide radicals as you would with regular integers, but you remember that the answers remain as radicals unless the number you're dealing with is a square (e.g. 9, 16, 25).
