Answer:

f(-2) + 9 is 19

Step-by-step explanation:

[tex]f(x) = - 3x - 2[/tex]

when x is -9:

[tex]f( - 2) = - 3( - 2) - 2 \\ f( - 2) = 10[/tex]

sum up with 9, f(-2)+9:

[tex]f( - 2) + 9 = 10 + 9 \\ = 19[/tex]

In two or more complete sentences, explain how to find the average rate of change of a function

Answers

You divide the change in the output value by the change in the input value.

only the beginning and ending data would be used to reveal average rate of change over the specified period of time. to find the average of change, divide the change in the output by the change in the input.

when given the value of a function at different points, calculate the average rate of change of a function for the interval between two values. calculate the difference between y2-y1 and x2-x1. then divide y/x to find the ratio.

A person riding in a elevator travels 240 feet in 30 seconds. What equation represents this relationship? How many feet will the person travel in 10 seconds?

A. y=8x; 8 feet
B. y=1/8x; 1.25 feet
C. y=8x; 80 feet
D. y=6x; 60 feet

Answers

The answer to this question is letter C

We can approach this by first finding the rate of feet per second traveled.

240(feet)/30(seconds)= 8 feet per second.

This answer resembles the slope for answer choice C.

To find the distance traveled in 10 seconds we do 10*8= 80 feet.

l3r-15l if r<5
SOLVE NOW PLEASE

Answers

Answer:

-3r + 15 ---> answer

Step-by-step explanation:

r < 5

You are going to multiply both sides with 3. The reason being is that 3 is a positive number and the equality sign will not change if you use +3.

3r < 15

Now, subtract 15 from both sides, you will get this:

3r < 15

-15 -15

-------------

3r — 15 < 0

Lastly, using the Modulus function, we are going to add a negative sign to the content of our previous step because it's already negative.

So, -3r + 15 is the final solution if r < 5 in the given equation of l3r-15l

Answer:

4 apples/ second

28800 apples in 2 hours

Step-by-step explanation:

20 apples / 5 seconds

Divide the top and bottom by 5

4 apples/ second

A few hours is 2 or 3

There are 3600 seconds in 1 hour

4 apples/ second * 3600 seconds / 1 hour = 14400 apples / hour

14400 apples/ hour

14400apples / hour * 2 hours

28800 apples in 2 hours

Answer:

4 apples per second; about 14400-43200 apples

Step-by-step explanation:

First, to find the unit rate, you need to divide the number of apples with the number of seconds...

20/5= 4 apples per second

Then, to find the number of apples being packed after a few hours, you multiply the unit rate of apples by the total amount of seconds...

(4)(3600) = 14400 apples

(4)(10800) = 43200 apples

And so on and so forth depending on the number of hours they need (remember to convert the hours into seconds and multiply by 4)
