A = L * W = 75 so L = 75/W Cost = 4W + 8(2L + W) = 4W + 16L + 8W = 12W + 16L = 12W + 1200/W C' = (12(W^2 - 100))/(W^2) = (12(W-10)(W+10))/(W^2) so W = 10 then L = 7.5
1) It’s true because -5 is way smaller than 3. All the negatives are below the 0 and everything below the 0 is lower than everything above the 0.
2) false. it’s false because in order -5 isn’t even close to 3
3) false.. It’s false because when you have those 2 line that are covering the -5 that means it’s “transforming” into a positive number. So therefore it’s would be 5>3 that would make it true.
4) True. it’s true because like I said the to lines mean the absolute value of something. So it’s being switch to a positive number
Hope this helps :)
Function number one , the graphing seems good
Each shirt costs 8 dollars.
4 Shirts 1 Pant
1 Pant=20 dollars
52 (total)-20=32
4shirts divides by 32= 8
So 8 dollars per shirt
