The solutions for the quadratic equation are given as follows:
x = -1, x = 7/5
<h3>What is a quadratic function?</h3>
A quadratic function is given according to the following rule:
y = ax^2 + bx + c
The solutions are:
In which:
![\Delta = b^2 - 4ac](https://tex.z-dn.net/?f=%5CDelta%20%3D%20b%5E2%20-%204ac)
For this problem, the equation is:
5x² - 2x - 7 = 0.
Hence the coefficients are a = 5, b = -2 and c = -7, and then the solutions are found as follows:
The solutions are:
x = -1, x = 7/5

1.5 cars per hour. 12*1.5=18
F(6)= 28, f(7)= 33, f(8)= 38, SO f(9)= 43
Y is the variable that suppose to be in that box i think
