PLEASE READ. It’s not asking for what n is it what the bottom next number would be, it’s asking for what the equation would be like n* 3+2

The bottom next number is -2.28 and the equation becomes , where n is the input value and O is the output value.

Step-by-step explanation:

The given values are,

                          Input                     Output

                              1                              2

                              2                             0

                              3                             -2

                              4                             -4

                                                           ?

Step:1

        Based on the input and output values assume the equation,

                          .....................(1)

       Where,

                 n - Input values

                 O - Output values

Step:2

        Check for solution,

                    Take, n = 1

                              O = 2 ( 2 - 1 )

                                  = 2 ( 1 )

                             O = 2

                     Take, n = 2

                               O = 2 ( 2 - 2 )

                                   = 2 ( 0 )

                               O = 0

                      Take, n = 3

                               O = 2 ( 2 - 3 )

                                   = 2 ( -1 )

                              O = -2

                      Take, n = 4

                               O = 2 ( 2 - 4 )

                                   = 2 ( -2 )

                               O = -4

            Now, we substitute the value for n = ,

                      Take, n =  

                               O = 2 ( 2 -   )

                                   = 2 ( 2 -  3.14 )                 ( ∵ = 3.14 )

                                   = 2 ( -1.14 )

                              O = -2.28

Result:

          The bottom next number is -2.28 and the equation becomes , where n is the input value and O is the output value.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

let's add {f(x)=x+1}f(x)=x+1 and {g(x)=2x}g(x)=2x together to make a new function.

f(x)+g(x) =(x+1)+(2x)=x+1+2x=3x+1

let's call this new function hh. so we have:

{h(x)}={f(x)}+{g(x)}{=3x+1}h(x)=f(x)+g(x)=3x+1

we can also evaluate combined functions for particular inputs. let's evaluate function hh above for x=2x=2. below are two ways of doing this.

method 1: substitute x=2x=2 into the combined function hh.

h(x)

h(2)

​    

=3x+1

=3(2)+1

=7

​ since h(x)=f(x)+g(x)h(x)=f(x)+g(x), we can also find h(2)h(2) by finding f(2) +g(2)f(2)+g(2).

first, let's find f(2)f(2):

f(x)

f(2)

​    

=x+1

=2+1

=3

​  

now, let's find g(2)g(2):

g(x)

g(2)

​    

=2x

=2⋅2

=4

​  

so f(2)+g(2)=3+4=\greend7f(2)+g(2)=3+4=7.

notice that substituting x =2x=2 directly into function hh and finding f(2) + g(2)f(2)+g(2) gave us the same answer!
