Firlakuza [10]

Answer:

Average rate of change = $11250 per year.

Step-by-step explanation:

Let's take two points from given information (2006, 90000) and (2010, 135000).

Now, use slope formula to find slope.

Slope = $\frac{y2-y1}{x2-x1}$

Use the two points to find average rate of change (slope)

Average rate of change = $\frac{135000-90000}{2010-2006}$

= $\frac{45000}{4}$

=11250

Average rate of change = $11250 per year.

Tema [17]

Answer:

length = 24 meters

Step-by-step explanation:

1. l = 2w

2. P = 2l + 2w

P=72

3. 72 = 2l + 2w

4. Substitute w=l/2 to solve for l

72 = 2l + 2(l/2) ---> 72 = 3L - Divide by 3 on both sides

L= 24 meters
