Well, 1000/5 would be smaller than 2000 not bigger. You are dividing into smaller pieces not multiplying into bigger ones.
2u-2u-4uequals 2u-2u+3+u+32
1: y=8, (-2,8)
2: y=6, (-1,6)
3: y=0, (2,0)
Step-by-step explanation:
Insert the x value into each equation then see what value of y that you need to get 4 on the right hand side of the equation.
The range is all positive values...
R{y | y>0}
Range > "Y" such that y is greater than 0
9/5 is the answer, hope this helps
