Answer:

y = (x - 4)² - 26

Step-by-step explanation:

To complete the square, all we need to do is take term -8x, and add enough to make the equation come out to the square of half that.  Half of -8 is -4, so we need to add 26 to the equation to end up at 16:

y = x^2 - 8x - 10\\y + 26 = x^2 - 8x + 16\\y + 26 = (x - 4)^2\\y = (x - 4)^2 - 26

Giving us the final result

kobusy [5.1K]

Answer:

Number of 1 $ bill = 20

Number of 5 $ bill = 6

Explanation:

 Let p represent number of one dollar bolls and q represent number of five bills.

A total of 26 bills are in a cash box.

      p + q = 26    ------------------------- Equation 1

The total amount of cash in the box is $50

      p + 5q = 50    ------------------------- Equation 2

Equation 2 - Equation 1,

        p + 5q - p -q = 50 - 26

        4q = 24

          q = 6

Substituting in equation 1.

         p + 6 = 26

         p = 20

Number of 1 $ bill = 20

Number of 5 $ bill = 6
