Answer:

7, -3/4, -3

Step-by-step explanation:

Note that all three of the given functions are linear. We can read the slopes directly from these functions: 7, -3/4, -3. Between any two values of x, the slope is exactly the same in each of these three functions.

Thus,

1) the average rate of change of f(x) = 7x - 4 over the interval [2,4] is 7.

2) the average rate of change of g(x) over the given interval is -3/4.

3) the average rate of change of h(x) over the given interval is -3.

What is the width of a rectangle with length 14cm and area 161 cm^2

Inessa05 [86]

Answer:

Step-by-step explanation:

The area of a rectangle can be found with the formula $A = l*w$ , where $l$ is the length of the rectangle and $w$ is the width.

From the given problem statement, we know that $l = 14$ and $A = 161$ , so we can fill in those values in the formula anbd solve for $w$ to get the width:
