Answer:

The answer to your questions is: 25 new teachers

Step-by-step explanation:

Data

# of students = 2000

ratio = 3:80 teachers to students

New teachers = ?

Process

I suggest to use rule of three to solve this problem

                     3 teachers ----------------  80 students

                      x                ----------------  2000 students

                  x = (2000 x 3) / 80 = 75 teachers

               Number of initial teachers = 75

The ratio change to 1:20

                     1 teacher -------------------  20 students

                     x             -------------------   2000 students

                     x = (2000 x 1) / 20

                    x = 100 teachers

Number of new teachers = 100 - 75 = 25

Calculate the average rate of change for the graphed sequence from n = 2 to n = 6.
ddd [48]

Answer:

  -3

Step-by-step explanation:

The average rate of change from point (x1, y1) to point (x2, y2) is given by ...

  m = (y2 -y1)/(x2 -x1)

For the given points, this is ...

  m = (2 -14)/(6 -2) = -12/4 = -3

The average rate of change on the interval is -3.

Given the functions f(x)=7-2x and g(x)=5x-3 find g(f(-4)) find f(g(x))
lara31 [8.8K]

Answer:

g(f(-4)) = -8

f(g(x)) = 13-10x

Step-by-step explanation:

g(f(-4)):

Plug in the equation f(x) into the variable x of g(x), we have:

(gof)= 5(7-2x)-3

Plug in x = -4 and the answer is -8

f(g(x)):
Plug in the equation g(x) into the variable x of f(x), we have:

7-2(5x-3) = 7-10x+6 = 13-10x
