Simple Interest Example:
Simple Interest
1 Year S.I = (1000 ×5 × 1)/100 = 50
2 Year S.I = (1000 × 5 × 2)/100 = 100
3 Year S.I = (1000 ×5 × 3)/100 = 150
If X is the number of hats . . . reading backwards . . .
Thursday = Wednesday + Tuesday
17 = 1/2 X + 5
Solving:
17 - 5 = 1/2 X
12 = 1/2 X
24 = X
So she had 24 on Monday.
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).
