Evaluate Piecewise Functions Pls Answer

Answers

Answer 1

Answer:

-23

Step-by-step explanation:

x = -5 lies in the last piece

h(-5) = 4(-5) - 3

= -20 - 3

= -23

Answer 2

Step-by-step explanation:

Step 1:  Find which piece-wise function it is in

Equation 1 → x < -7

Let x = -5 → (-5) < -7 ← False

Equation 2 → -7 ≤ x < -5

Let x = -5 → -7 ≤ (-5) < -5 ← False

Equation 3 → x ≥ -5

Let x = -5 → (-5) ≥ -5 ← True

Step 2:  Find the value of h(-5)

\(h(-5) = 4x - 3\)

\(h(-5) = 4(-5) - 3\)

\(h(-5) = -20 - 3\)

\(h(-5) = -23\)

Answer:  \(h(-5) = -23\)

Evaluate (whith steps) -3 - 5 (8 + 4) + 16 - 32

Answers

Answer:

Using the order of operations (PEMDAS), we evaluate the expression as follows:

First, we perform the operations inside the parentheses: 8 + 4 = 12.

Next, we multiply 5 by 12: 5(12) = 60.

Then, we combine the like terms: -3 - 60 + 16 - 32 = -79.

Therefore, -3 - 5 (8 + 4) + 16 - 32 = -79.

The answer is -79 ( I think )

How did you decide where to place your line of best fit? Describe your reasoning.Based on your data,

Answers

Answer:So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.

So basically the units are counting up by 5.

The x axis is age in years and y axis is the number of US states named in 60 seconds.

Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.

(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)

Answers

Answer:

14x43=602 babies

Step-by-step explanation:

Is this the whole context of the problem? Going off of the idea that 14 babies are born every year each year the amount of birds would increase by 14. For example after two years (14x2) there would be 28 birds then after three years (14x3) there would be 42 so on so forth.

602 because 14 times 43 equals 602 since she keeps have babies for the next 43 years
