Answer:
   (x, y) = (-0.6, 0.8)  or  (1, 4)
Step-by-step explanation:
Use the second equation to substitute for y in the first.
  (x -1)² +((2x +2) -2)² = 4
   x -2x +1 + 4x² = 4 . . . . . . . eliminate parentheses
   5x² -2x -3 = 0 . . . . . . . . . . subtract 4, collect terms
Now we can rearrange the middle term to ease factoring by grouping.
   (5x² -5x) +(3x -3) = 0
   5x(x -1) +3(x -1) = 0 
   (5x +3)(x -1) = 0
The values of x that make these factors zero are ...
   x = -3/5, x = 1
The corresponding values of y are ...
   y = 2(-3/5)+2 = 4/5 . . . . for x = -3/5
   y = 2(1) +2 = 4 . . . . . . . . for x = 1
The solutions are: (x, y) = (-3/5, 4/5) or (1, 4).

You'll use the chart to start your equation. There are 2000 grams to a kilogram. One batch is 1425grams. To get 2 kilograms she needs 2000 grams. So 2000-1425= your answer. For question 2, there are 1000 ml in 1 Liter. Use this information to see which will hold more liquid, 2 bottles or 8 cans.
