Nicole used 3/8 of her ribbon to wrap a present. if she used 6 feet of ribbon for the present, how much ribbon did nicole have at first? i cant even begin to figure out how to determine what the first step is,

Your answer is 8 feet.

Here are the steps:

Let the length of the ribbon be x.

Take 6x over 8 (6x/8) which equals 6.

Then, take 3x/4 which also will be 6 in this case.

3x = 24

x = 24 over 3 (24/3)

x = 8.

Hope this helped :)

range is infinite on both x and y axis positive and negative

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.
