<em><u>QUADRATIC EQUATION:</u></em>
ax² + bx + c = 0 where a ≠ 0
The sign of the discrimant (b² - 4ac) determines the number of real-number solutions :
- If the discrimant is positive, the equation has <em><u>two real-number solutions</u></em>.
- If the discrimant is equal to zero, the equation <em><u>has one real-number solution</u></em>.
- If the discriminant is negative, the equation has <em><u>no real-number solution</u></em>.
The solutions of the equation, also called roots, can be obtained with the QUADRATIC FORMULA :
---------------------------------------------------------------
▪️ x² + 7x + 10 = 0
(1) Substitute the letters in the general quadratic equation with their values in the given expression:
(2) <em>Determine the sign of the discriminant: </em>
The discrimant is positive ; the equation has two real-number solutions.
(3) <em>Determine the roots of the equation :</em>
Therefore, x = -5 or x = -2

Answer: 22 small snow cones and 34 large snow cones were sold.
Step-by-step explanation:
Let x represent the number of small snow cones that were sold.
Let y represent the number of large snow cones that were sold.
Selena's snow cone stand sells small snow cones for $2 and large snow cones for $3.50. One summer day, she sold $163 worth of snow cones. This means that
2x + 3.5y = 163 - - - - - - - - - - 1
If the number of large snow cones sold was 12 more than the number of smalls snow cones, it means that
y = x + 12
Substituting y = x + 12 into equation 1, it becomes
2x + 3.5(x + 12) = 163
2x + 3.5x + 42 = 163
5.5x = 163 - 42
5.5x = 121
x = 121/.5 = 22
y = x + 12 = 22 + 12
y = 34
