What is the solution to = n/4 -12.4?

I need the rest of the question

Step-by-step explanation:

Sorry I want to help you but I cant unless there is a (example): 12+-3= n/4 -12.4

or a list of options to choose from like what will equal 6? A.2 B.3 C.100 D.9

if you give me the rest I can solve, thanks :)

n=-49.6

Step-by-step explanation:

multiply both sides by 4 becasue multiplication is inverse of division.

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.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
