The last one (0, -3) because it doesn’t move to the left/right, only up/ down.
Answer:
2 bills and 1 coin
Step-by-step explanation:
Given

Required
Fewest number of bills and coins she can get receive as change
FIrst, we need to calculate her change
Change = Amount Paid - Lite


Next is to split the change to bills and coins

The $5 and $1 makes 2 bills while the 50 cents makes 1 coin.
<em>Hence, the minimum she could receive is 2 dollar bills and 1 coin as change</em>
<em></em>

3X -3 => 9
3X => 9+3
3X => 12
3X/3 => 12/3
X => 4

<h3>
You need to add 4 to both sides</h3>
The x term has a coefficient of 4. Take half of this to get 2, then square it to get 4. This is the value we add to both sides to get x^2+4x+4 = 5. Note how x^2+4x+4 factors into (x+2)^2
---------
Another example: Let's say we started with x^2+6x = 1. To complete the square, we need to add 9 to both sides. I start with 6 (the x coefficient) and cut that in half to get 3, then I squared that to get 9. So we add 9 to both sides getting x^2+6x+9 = 10 which becomes (x+3)^2 = 10
There is some info missing to be able to solve.
