To get the x-intercepts of the function, f(x) = 4x2 – 24x + 20
It has to be equated to zero and the values of x are the x-intercepts. So,
4x2 – 24x + 20 = 0
The resulting equation is a quadratic equation which can be solved by different methods. The solution is
x = 5, 1
The average therefore is:
(1+5/)2 = 3
Answer:
-0.8 or -4/5
Step-by-step explanation:
You could do this a couple of ways. If you wanted to change your equation into slope-intercept form to make it easier for you, then you can do as follows:
4x + 5y = 10
5y = -4x + 10
y = -4/5x + 2
So your slope is -4/5.
Or you could do -A/B when your equation is in standard form. A is the term in front of the x value and B is the term in front of the y. Both strategies give you -4/5 for the slope.
