Answer:

$38 for 2 sweaters

Step-by-step explanation:

Every price for all other sweater options are divisible by 24, since it is the unit price (meaning 1 sweater = $24). 38 is not divisible by 24, but by 19. This means it does not follow the unit price. It would be a special sale.

Answer:

By the end of this resource, you will be able to identify domain and range from any given contextual situation.  

Determining the domain and range from a linear or quadratic contextual situation is similar to determining the independent and dependent variables.

Step-by-step explanation:

Suppose you are interviewing for a job. Your employer offers you the choice of two different options for your pay. The first option is to pay you $10.00 per hour and give you a raise of $.50 per hour at the end of the year. The second option is to pay you $11.50 per hour and give you a raise of $.25 per hour at the end of the year.

First, find a function for each option. To do that, you have to know what the domain and range might be. Let y = the amount you will make at the end of the year and x = the number of hours you work. Thinking about what would be reasonable values for x and y will help determine the domain and range.

First, let's think about the domain. Since x represents the numbers of hours you worked for the year, would it be reasonable to have negative values? If you said NO, you would be correct. We can assume the lowest possible value in the domain would equal zero. So, our domain would be {x| x ≥ 0}.

Now, let’s think about the range. Since y represents your earnings at the end of the year, would it be reasonable to have negative values? If you said NO again, you would be correct. You cannot earn a negative amount. We can assume the lowest possible value in the range would also equal zero. So, our range would be {y | y ≥ 0}. You should be able to relate with this situation since you may have to make a decision in comparing two or more job offers in your future.

It's important to realize that every situation is different and you must think about what is reasonable.  

Answer:

D. y = 9/4x

Step-by-step explanation:

First, find the gradient or slope, m

m = change in y ÷ change in x

m = (0 - -9) ÷ (0 - -4)

m = 9 ÷ 4 = 9/4

There is no y intercept, since the line goes through the origin (0,0)

y = 9/4x

Answer:

D.) y=9/4x

Step-by-step explanation:

The graph that I did has the line going through (0,0) and (-4,-9), like the question states.

Answer:

The flagpole is 12 feet

Step-by-step explanation:

The boy's shadow is half of the flagpole's shadow. So the flagpole is 2 times as much as 6 ft because the boy is six feet. 6 x 2 = 12. So the final answer is 12 ft.

Answer:

f(8f + 7)

Step-by-step explanation:

8f^2 + 7f

= f(8f + 7)

The factor of 8f² + 7f is f(8f + 7).

Factorization in mathematics is the process of dividing a large number into smaller ones that, when multiplied together, give you the original number. Factorization is the process of dividing a number into its components or divisors.

Given:

An expression,

8f² + 7f.

To find the factor:

8f² + 7f,

= f(8f + 7)

Therefore, f(8f + 7) is the factor.

Answer:

D. y = |x + 5| - 2

Step-by-step explanation:

The peak of the graph is formed at the point (2, 5)

that means the function must be such that the value of y is 5 when x is 2.

Checking D option:

y= | x + 5| - 2

5 = | 2 + 5| - 2

5 = 7 - 2

5 = 5

LHS = RHS

this means that the given graph is represented by the equation in option D.

Therefore, it's D

_________________

You'll have to check for all options by placing the values of x and y repetitively in all of them.

There, LHS ≠ RHS.

Answer:

a. y = -2x-5

Step-by-step explanation:

*Don't get confused the y-axis scale is 2

I guess you would kind of have to guess by looking at the graph for this one, the y-intercept is 5.

The graph is negative because it is pointing the opposite way

The slope is 2 because the y-axis has a scale of 2

With these facts you can formulate that the equation would be y = -2x-5

Answer:

what chart??????????????????????????????????????????

Step-by-step explanation:

The number of arrangements is an illustration of permutations.

The number of arrangement is 5040

The given parameter is:

[tex]n = 7[/tex] --- number of days

[tex]r = 7[/tex] --dinners for 7 days

So, the number of different arrangement is

[tex]^nP_r = \frac{n!}{(n - r)!}[/tex]

Substitute known values

[tex]^7P_7 = \frac{7!}{(7 - 7)!}[/tex]

[tex]^7P_7 = \frac{7!}{0!}[/tex]

[tex]^7P_7 = \frac{5040}{1}[/tex]

[tex]^7P_7 = 5040[/tex]

Hence, the number of arrangement is 5040

Answer:

Step-by-step explanation:

X:2

Y:4

Z:6

The values that best complete the chart as per the concept of ratio are X:2, Y:4, and Z:6.

To determine the correct values for the chart, let's analyze the given information about an object moving at a constant acceleration:

The first column represents time in seconds (0, 1, 2, 3).

The second column represents velocity in meters per second (0, X, Y, Z).

Since the object is moving at a constant acceleration, its velocity is changing by the same amount in equal time intervals.

We can use the formula for constant acceleration:

Velocity (V) = Initial Velocity (U) + (Acceleration × Time)

Given that the object starts from rest (initial velocity, U = 0), we can deduce the following:

At time 1 second (T = 1), the object's velocity is X m/s.

At time 2 seconds (T = 2), the object's velocity is Y m/s.

At time 3 seconds (T = 3), the object's velocity is Z m/s.

Based on this information, the correct values for the chart are:

X: 2 (Velocity at 1 second is 2 m/s)

Y: 4 (Velocity at 2 seconds is 4 m/s)

Z: 6 (Velocity at 3 seconds is 6 m/s)

Answer:

100

Step-by-step explanation:

Since, line a is parallel to line t ( from diagram ).

x - 30 and 70 are alternate interior angles.

Reason : -

Alternate interior angles are equal when two lines are parallel and cut by a transversal line.

x - 30 = 70

x = 70 + 30

x = 100
