Answer:

6 ≤ x ≤ 12

Step-by-step explanation:

Instead of solving the area as 1.5*4x, you would do 6*x (multiply 1.5 by 4 and divide 4x by 4).

Then, you can just use division to find the answer.

36/6=6

72/6=12

And since 36≤A≤72, the area can be any number between 36 and 72, so x can be any number between 6 and 12.

Determine the value of f(2) that will lead to an average rate of change of 15 over the interval [2,6]. (HELP PLEASE)

Fofino [41]

Average Rate of Change/Slope Formula: $\frac{y_2-y_1}{x_2-x_1}$

So using points (6,71) and (2,y), and the slope of 15, plug them into the slope formula as such:

$\frac{71-y}{6-2}=15$

From here we can solve for y. Firstly, solve the subtraction:

$\frac{71-y}{4}=15$

Next, multiply both sides by 4:

$71-y=60$

Next, subtact both sides by 71:

$-y=-11$

Lastly, multiply both sides by -1, and <u>your final answer will be $y=11$ , or A.</u>
