Solve for f:
f - 4 = 6f + 26

f= -6

Step-by-step explanation:

f - 4 = 6f + 26

Subtract f from each side

f-f - 4 = 6f-f + 26

-4 = 5f +26

Subtract 26 from each side

-4-26 =5f+26-26

-30 = 5f

Divide each side by 5

-30/5 = 5f/5

-6 = f

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%

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.
