Answer:

(4,-20)

Step-by-step explanation:

midpoint ((x1+x2)/2, (y1+y2)/2)

Let S be (x,y(

(0+x)/2=2, solve for x, x=4

(4+y)/2=-8, solve for y, y=-20

Question 3

crimeas [40]

Answer:

D = 141

Step-by-step explanation:

The given quadratic equation is

$5x^2+9x=3\\\\5x^2+9x-3=0$ .

It is required to find the value of the discriminant. The value of discriminant of any quadratic equation is given by :

$D=b^2-4ac$

Here, a = 5, b = 9 and c = -3

On plugging all the values, we get :

$D=(9)^2-4\times 5\times (-3)\\\\D=141$

So, the value of discriminant for y is 141.
