Kelly's little brother is exactly 3 feet tall. How tall is he in inches?

he is 36 inches

Step-by-step explanation:

36 inches

Step-by-step explanation:

We know that Kelly's little brother is exactly 3 feet tall, and we know how big he is in inches.

To solve first keep in mind that 1 feet is 12 inches.

Therefore if there are 3 feet, we would multiply the inches 3 times.

12 * 3

= 36

Therefore, Kelly's little brother is 36 inches.

Step-by-step explanation:

Let's call y the number of patients treated each week

Let's call x the week number.

If the reduction in the number of patients each week is linear then the equation that models this situation will have the following form:

Where m is the slope of the equation and b is the intercept with the x-axis.

If we know two points on the line then we can find the values of m and b.

We know that During week 5 of flu season, the clinic saw 90 patients, then we have the point:

(5, 90)

We know that In week 10 of flu season, the clinic saw 60 patients, then we have the point:

(10, 60).

Then we can find m and b using the followings formulas:

  and

In this case: and

Then:

And

Finally the function that shows the number of patients seen each week at the clinic is:
