Answer:

(D) \dfrac{f(9)-f(2)}{9-2}

Step-by-step explanation:

To determine the average rate of change in f(x) over the interval [a,b], we use the formula:

\text{Average rate of change}=\dfrac{f(b)-f(a)}{b-a}

Therefore, given a function f(x), the average rate of change in f(x) over the interval [2,9] is given as:

\text{Average rate of change}=\dfrac{f(9)-f(2)}{9-2}

The correct option is D,

A video game store allows customers to rent games for $4.75 each. Customers can also buy a membership for $54 each year, and vid
Nezavi [6.7K]

Answer:

24

Step-by-step explanation:

Cost of membership + game = 2.50x + 54

Cost of just games = 4.75x

The catch is, how do we make up the 54 dollars?

So equate the 2 costs

4.75x = 2.50x + 54      Subtract 2.50

4.75x - 2.50x = 54       Combine

2.25x = 54                    Divide by 2.25

x = 54/2.25

x = 24

That means that 24 is the break even point.

12-(4) - 1<br> 2<br><br> Please helppp!!! :)
Kryger [21]

Answer:

17

Step-by-step explanation:

Simplify:

12\frac{1}{2} = \frac{25}{2}  

-4\frac{1}{2} = \frac{-9}{2}

\frac{25}{2} - (\frac{-9}{2} ) = \frac{25}{2} + \frac{9}{2} = \frac{34}{2} = 17

When you have a subtraction sign next to a negative number, the negative number will turn positive since it's understood as -1 multiplied by the number when it's a negative number.

Two supplementary angles are congruent. Which equation gives the measure in degrees, d, of each angle?
Nimfa-mama [501]

Solution:

The given statement is :Two supplementary angles are congruent.

Two angles are said to be supplementary if sum of these two angles is 180°.

Let one Angle be A, then another angle will be 180 - A.

As given:

A≅180-A

A=180 -A

A +A= 180

2 A = 180

Dividing both sides by 2, we get

A= 90°

The Measure of each angle will be of 90°.

i.e , d = 90°
