Helpppppppp will mark brainlest​
Shkiper50 [21]

Answer:

-8

Step-by-step explanation:

what do you think, when you look at the examples given in the problem definition ?

don't you see the pattern, that f(x) = x+2 ?

f(1) = 1+2 = 3

f(2) = 2+2 = 4

f(3) = 3+2 = 5

so, if we follow this assumption, then

f(-10) = -10 + 2 = -8

PLEASE HELP!! this is due really soon
GuDViN [60]

Answer:  There are 467 students at Holmes Junior High.

              There are 342 students at Harper Junior High.

_________________________________________________

Step-by-step explanation:

_________________________________________________

Let " x" represent the number of students at Harper Jr. High.

Holmes Junior has:  " (x + 125) "  students .

Harper Junior High has:  " x"  students:

_________________________________________________

Together, the total number of students equal:  " 809 " students.

so:  " x + (x + 125) = 809 " .

We want to solve for "x" and " (x + 125)" .

We want to solve for "x" ;  

then we can solve for " (x + 125) "  by adding "125" ;

                                                      to our "solved value for "x" ;

____________________________________________

  x + (x + 125)  = 809 .

 →  1x + 1x + 125 = 809 ;

 →   2x + 125 = 809  ;

Now, subtract "125" from each side of the equation:

 →   2x + 125 - 125 = 809 - 125 ;

 →   2x  =  684 ;

Now, divide each side of the equation by "2" ;

    to isolate:  "x" on one side of the equation; & to solve for "x" ;

 →   2x/ 2 =  684 / 2  ;

to get:

 →    x = 342 ;  which is the total number of students at Harper Jr. High.

Now,  to solve for:  " (x + 125)" ;

Plug in:  "342" for "x" ;

→  " (342 + 125) " = " 467 " '

→  which is the total number of students at Holmes Jr. High.

_________________________________________________

Do our answers make sense:

Does:  " 342 + 467 =?  809 ?? " ;

         →  Yes!

_________________________________________________

Answer:  There are 467 students at Holmes Junior High.

               There are 342 students at Harper Junior High.

Determine whether each equation has one solution, no solution or infinitely many solutions. 4x + 10 = 2(2x + 5) 4x - 5 = 4x + 10
sdas [7]

Answer:

see below

Step-by-step explanation:

4x + 10 = 2(2x + 5)

Distribute

4x+10 = 4x+10

Since the left side is identical to the right side, there are infinite solutions

4x - 5 = 4x + 10

Subtract 4x from each side

-5 = 10

This is never true, so there are no solutions

4x-5 = -5

Add 5 to each side

4x = 0

x=0

There is one solutions
