The number of airline passengers in 1990 was 466 million. The number of passengers traveling by airplane each year has increased

Answer:

The solutions are (-√6,0) and (√6,0)

(-√5,-1) and (√5,-1)

Step-by-step explanation:

We start with the equations:

and

Rearranging the second equation to make y the subject results in;

Substituting into the first equation gives us:

and

The solutions remain as (-√6,0) and (√6,0)

(-√5,-1) and (√5,-1)

Solution:

We know, g(x) = f(x) + k --------(1)

It is given that f(x) = (x+2)

and g(x) = (x+5)

Substituting f(x) and g(x) into equation (1):

→ (x+5) = (x+2) + k

→ = k

→ k =

Thus, the value of k is 1.

Answer:

When you divide 360 by 5, you get 72; a full circle measures 360 degrees
