2. Mark Antonio uses online banking. He pays the basic charge, pays 8 bills, and has a lost card replaced. He also has ATM charges that include 2 national network and 2 out-of-network transactions, and a $33 cash advance. What are his total fees for the month?

the answer would be c:   ax + b = ax + c

step-by-step explanation:

you can't solve x because it is 2 linear equation and you only have one equation

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.
