In the following quadratic equation identify the values of a, b, and c that you would use in the quadratic formula.
7x^2-3x+9=0
A. a=7 b=-3 c=9
B. a=9 b=7 c=-3
C. a=-7 b=3 c=-9
D. a=7 b=3 c=9

A

Step-by-step explanation:

Let's first define what exactly the values of a, b, and c represent.

- a: this is the coefficient of the x^2 term

- b: this is the coefficient of the x term

- c: this is the constant term (no variable attached)

Our equation is: y = 7x^2 - 3x + 9.

The coefficient of x^2 is 7, so a = 7. The coefficient of x is -3, so b = -3. And finally, the constant term is 9, so c = 9.

Thus, the answer is A.

The general quadratic equation is ax^2 + bx + c = 0

=> Here, we have: 7x^2 - 3x + 9 = 0 <=>  7x^2 + (-3)x + 9 = 0

=> a = 7, b = -3, c = 9

=> Option A is correct.

Hope this helps!

do you have the measurements?

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
