Triangle PQR has vertices P(4,-1),Q(-2,7), and R(9,9). Find an equation of the median and altitude from R.
Reil [10]
If we are drawing altitude from R the PQ will be base of this triangle. So we can say Median from R will cut on Midpoint of PQ. So firstly we will find mid point of PQ Which is S given as below:
P(4,-1) , Q (-2,7)

Let Co-ordinate of S is (x,y)
So x =  \frac{x_1+x_2}{2}
x =  \frac{4-2}{2} =  \frac{2}{2} = 1

y =  \frac{y_1+y_2}{2}
y =  \frac{-1+7}{2} =  \frac{6}{2}= 3
So midpoint of PQ is S(1,3).

Now we can find equation of RS
Co-ordinate of R is (9,9) and and S is (1,3).

In general equation of line from two point (x_1 , y_1) and (x_2,y_2) is
(y-y_1) =  \frac{y_2-y_1}{x__2-x_1}(x-x_1)

So equation of RS is

(y-9) =  \frac{9-3}{9-1} (x-1)
(y-9) =  \frac{6}{8}(x-1)
8(y-9) = 6(x-1)
8y-72 = 6x - 6
-72+6 = 6x - 8y
-66 = 6x-8y

So the equation of median is 6x - 8y = -66

The sum of the roots of 2x squared + 8x -3=0 is?
Helen [10]
According to Vieta's formula, if x_1,x_2 are solutions of quadratic equation ax^2+bx+c=0, then:

\displaystyle x_1+x_2=- \frac{b}{a}

In our case:

\displaystyle x_1+x_2=- \frac{8}{2} =-4
