The endpoints of a side of rectangle ABCD in the coordinate plane are at A (3,9) and B(5, 1). Find the equation of the line that contains the given segment.
The line segment is CD and point C is at (9,2).
The equation is

y = - 4x + 38

Step-by-step explanation:

A(3, 9)

B(5, 1)

= = - 4

CD║AB

C(9, 2)

y - 2 = - 4(x - 9)

y = - 4x + 38

345

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
