There are 15 students for every teacher in a school. A) How many students are there if there are 10m teachers? B) How many teachers are there if there are 6m students? Evaluate the expression when m = 20.

10m teachers,

10m(15) = 150m students

When m = 20,

3000 students

5m students,

6m/15 = ⅖m teachers

When m = 20,

⅖(20) = 8 teachers

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2
