Answer:

Percent makes the number go back two spaces so 15% becomes 0.15

85 x 0.15 = 12.75

12.75 is the discount so we subtract that off.

85-12.75=72.25

$72.25 would be the answer

Step-by-step explanation:

Answer:

75.25

Step-by-step explanation

A coupon for 15%off means it only costs (1-0.15) times the original price

So, 85.00*0.85=72.25

Which equation of the solutions of x2 = -7x – 8
timama [110]

Answer:

x = 1, -5.56

Step-by-step explanation:

x^2 = -7x - 8

shift -7x and -8 to the other side . Remember when u shift minus changes into plus.

x^2 + 7x + 8 = 0

using quadratic equation formula

in quadratic equation one value comes positive and other comes in negative

a = 1  , b = 7 and c = 8

taking positive sign

x = (-b + \sqrt{b^2 - 4*a*c}) /2*a

x = (-7 + \sqrt{7^2 - 4*1*8} ) /2*1

x = (-7 + \sqrt{49 + 32} ) /2

x = (-7 + \sqrt{81} )/ 2

x = -7 + 9 / 2

x = 2/2

x = 1

taking negative sign

(-b - \sqrt{b^2 - 4*a*c} ) /2*a

x = (-7 - \sqrt{7^2 - 4*1*8} ) /2*1

x = (-7 - \sqrt{49 - 32} ) /2

x = -7 - \sqrt{17} / 2

x = -7 - 4.12 / 2

x = -11.12/2

x = -5.56

therefore x = 1 , - 5.56
