Alandscape supply business charges $35 to deliver mulch. the cost of the mulch is $29.
per cubic yard. write and solve a linear equation to find the cost of having 6 cubic yards
of mulch delivered to a site.
slope intercept form

$209

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is equal to

where

m is the slope

b is the y-coordinate of the y-intercept (initial value)

Let

x ----> the volume of mulch in cubic yards

y ----> the total cost in dollars

we have that

The slope of the linear equation is

----> flat fee to deliver mulch

The linear equation is

For x=6 yd^3

substitute in the equation and solve for y

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.
