Answer:

No solution

Step-by-step explanation:

y = 2x + 4 (1)

-2x + y = -5 (2)

Rewrite equation (2)

y = 2x - 5

So now you have 2 equations

y = 2x + 4 (1)

y = 2x - 5 (2)

----------------------------------Subtract

0 = 9

As you know 0 is not equal 9

Answer:

$y = 300 (2)^x$

Where x represent the number of period of times of 22 minutes. If we want to know the value of the population after 66 minutes we need to find the value of x on this way:

$x = 66 minutes *\frac{1period}{22 minutes}= 3$

So then we need to replace the value of x =3 and we got:

$y= 300 (2)^3 = 2400$

Step-by-step explanation:

For this case we have the following function:

$y = 300 (2)^x$

Where x represent the number of period of times of 22 minutes. If we want to know the value of the population after 66 minutes we need to find the value of x on this way:

$x = 66 minutes *\frac{1period}{22 minutes}= 3$

So then we need to replace the value of x =3 and we got:

$y= 300 (2)^3 = 2400$
