Heather has $45.71 in her savings account. she bought six packs of markers to donate to her school. write an expression for how much money she has in her bank account after the donation
has to match one of those
a. 45.71+6m
b. 45.71−6
c. 45.71+6
d. 45.71−6m

D. 45.71 - 6m

Step-by-step explanation:

     Let m = the cost of a marker

Then 6m = the cost of six markers

Heather is paying for these from her savings account.

After deducting the cost of the markers, the amount in her account will be

45.71 - 6m

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.

nope.   happens to me as well.
