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

x = 5 and x = 1

The average is the midpoint

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

What are the coordinates of the centroid of a triangle with vertices J(−4, 2) , K(2, 4) , and L(0, −2) ?

kodGreya [7K]

<span>To begin you have to find the midpoint of the side with (2,4) and (-4,2) as vertexes. [ 2 + -4 ] / 2, [ 2 + 4 ] / 2 ) = (-1, 3) Then you have to find the point 2/3 of the distance from (0,-2) to (-1,3) = (0 + (-1 - 0) (2/3) , -2 + ( 3 - -2)(2/3) ) ( 0 - 2/3, -2 + (5)(2/3) ) (-2/3, -2 +10/3 ) The coordinates of the centriod of a triangle are (-2/3 , 4/3 )</span>
