Nina knows that the average of the x-intercepts represents the line of symmetry for a quadratic function through the x-axis. Whi
Romashka [77]

Answer:

\bf \displaystyle\frac{5+1}{2}=\displaystyle\frac{6}{2}=3

Step-by-step explanation:

The x-intercepts are the values of x for which y=0, that is f(x)=0.

The x-intercepts of  

\bf f(x)=4x^2-24x+20

are the values of x such that

\bf 4x^2-24x+20=0

Divide both sides by 4 to simplify a little

\bf x^2-6x+5=0

Solve the quadratic equation

\bf x=\displaystyle\frac{-(-6)\pm\sqrt{(-6)^2-4*1*5}}{2*1}=\displaystyle\frac{6\pm\sqrt{36-20}}{2}=\\\\=\displaystyle\frac{6\pm\sqrt{16}}{2}=\displaystyle\frac{6\pm4}{2}

and you get the 2 x-intercepts

x =10/2  and x = 2/2  

or

x = 5 and x = 1

The average is the midpoint

\bf \displaystyle\frac{5+1}{2}=\displaystyle\frac{6}{2}=3

vlabodo [156]

Answer: 123,060

So you multiply 1700 by 12 then add 110 then divide by 12 to see how much you would now pay a year, which would be 1709 (new monthly payment) then multiply that by six years 12 month's time 6 years = 72 months so multiply 1700 times 72 and you get 123060
