Which of the following is a solution of x^2 - 2x = -8?
Zina [86]
X^2-2x=-8  add 1 to both sides

x^2-2x+1=-7  now the left side is a perfect square

(x-1)^2=-7  take the square root of both sides

x-1=±√-7  add 1 to both sides

x=1±√-7 which is

x=1±i√7  so

x=1+i√7 and 1-i√7

Please help me ‍♀️ im a tad bit slow-

Answer:

  • Michelle
  • $5

Step-by-step explanation:

The dollar value of the 20% coupon will increase if the discount is from a larger amount. Applying the $25 coupon first reduces the amount that the 20% applies to, so reduces the dollar value of the 20% coupon.

Michelle used the 20% coupon first, so its value was 20%($100) = $20.

Natasha used the $25 coupon first, so the value of the 20% coupon was ...

  20%($100 -25) = 20%(%75) = $15.

Michelle paid $20 -15 = $5 less.
