3. Consider the expression 4x + 15.

Softa [21]

Example of a real world problem:
Chris is starting a handmade card business. In the beginning, he starts off with 15 cards and makes 4 new cards every week.

The variable (x) would represent the number of weeks that passed.

Example 2:
Sam decides to start saving up money to buy a video game. She starts off with 15 dollars and gets an allowance of 4 dollars every day.

The variable (x) would represent the number of days that pass.

To come up with your own equation, most times, x represents a unit of time. The zero value (the number that isn’t being multiplied by a variable) in the equation always represents your starting value, and the coefficient of the variable represents how much of something is being gained or added after a duration of time.

I hope this helps!

Choose the correct solution and graph for the inequality. -x/4=<2

Radda [10]

Answer:

Step-by-step explanation:

$\frac{-x}{4} \leq 2$ multiply both sides by 4, that way we will simplify the fraction

-x $\leq$ 8 and we need to multiply this by -1

-8 $\leq$ x the graph that represents this inequality is given in D.

Students in a class are asked to stand in ascending order according to their heights for the annual class photograph. Determine

horrorfan [7]

Answer:

The function in Python is as follows:

def heightChecker(heights):

expected = []

count = 0

for i in range(len(heights)):

expected.append(heights[i])

expected.sort()

for i in range(len(heights)):

if expected[i] != heights[i]:

count+=1

return count

Step-by-step explanation:

Required

Function to return the number of out of position students

See comment for complete question

This defines the function. It receives the heights as a parameter, from the main

def heightChecker(heights):

This initializes a list, (expected list)

expected = []

This initializes the count of out of position students

count = 0

This iterates through the original list

for i in range(len(heights)):

The list item is then appended to the expected list

expected.append(heights[i])

This sorts the expected list in ascending order

expected.sort()

This iterates through the original and the expected lists

for i in range(len(heights)):

If list elements at the same index are not the same, count is incremented by 1

if expected[i] != heights[i]:

count+=1

This returns count

return count
