PLEASE i AM CRYING RIGHT NOW I HAVE HAD NO SLEEP AND I DONT KNOW THE ANSWER PLEASE
1 answer:
c = number of children tickets sold
a = number of adult tickets sold.
we know that 178 total tickets were sold, thus whatever "c" and "a" are, c + a = 178.
the price of a child ticket is $5.4, so the price for all "c" tickets must be 5.4c.
the price of a adult ticket is $9, so the price for all "a" tickets must be ac.
we also know the total sales for all tickets combined is $1310.4, so then 5.4c + 9a = 1310.4.

Using the discriminant, the quadratic equation that has complex solutions is given by:
x² + 2x + 5 = 0.
<h3>What is the discriminant of a quadratic equation and how does it influence the solutions?</h3>A quadratic equation is modeled by:
y = ax² + bx + c
The discriminant is:
The solutions are as follows:
- If
, it has 2 real solutions.
- If
, it has 1 real solutions.
- If
, it has 2 complex solutions.
In this problem, we want a negative discriminant, hence the equation is:
x² + 2x + 5 = 0.
As the coefficients are a = 1, b = 2, c = 5, hence:
