Solve the Quadratic Equation

Mathematics
1 answer:
UNO [17]3 years ago
7 0

Answer:

-4.54 and 1.54

Step-by-step explanation:

This is a quadratic equation

Let Δ be our discriminant :

  • a= 1
  • b= 3
  • c= -7
  • Δ = 3²-4*1*(-7)= 37≥0

so we have two solutions : x and y

x =( -3-\sqrt{37})/2 = -4.54

y= ( -3+\sqrt{37})/2= 1.541

then the solutions are -4.54 and 1.54

A book costs $1.49 and is sold in a retail store for $8.99. What is the percentage in mark up? *​
Alex777 [14]

Answer:

603.35%

Step-by-step explanation:

Given that a book costs $ 1.49 and is sold in a retail store for $ 8.99, to determine what is the percentage in mark up, the following calculation must be performed:

1.49 = 100

8.99 = X

8.99 x 100 / 1.49 = X

899 / 1.49 = X

603.35 = X

Thus, the mark up percentage of the book is 603.35%, which implies an increase of more than 6 times its initial value.
