Write the equation fully simplified slope intercept form

y = -1/5x - 1

Step-by-step explanation:

The line crosses the y axis at -1, making it the y-intercept.

Since the line is going downwards from left to right, we know that it is a negative slope.

The line goes down one and 5 right. That makes the slope -1/5.

The equation is y = -1/5x - 1

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

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.
