(2 4/5) x (-5 2/3) whats the answer I need help

4/5

Step-by-step explanation:

5(y + 2) = 4(x - 3)

Divide each side by 5

5/5(y + 2) = 4/5(x - 3)

(y + 2) = 4/5(x - 3)

This is in point slope form

(y  - y1) = m(x - x1)

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.
