C is the correct answer.

The value of a baseball​ player's rookie card began to increase once the player retired. When he retired in 1998 his card was worth ​$8.39. The value has increased by ​$2.16 each year since then. Express the relationship relating the value of the card y in dollars and the number of years x the player has been in retirement with an equation. Is the relationship between x and y​ proportional? What was the value of the card in 2009​?

Answers

8.39+2.16•x=y

x=years after retirement
y=final value of the card

no it is not proportional

2009 is 11 years after the players retirement, sub 11 for x

The equation would be 8.39 + 2.16x = y;
To get x you would want to subtract 2009 by 1998. You get 11 (years). So 8.39 + 2.16 • 11 = $32.15.

Caitlin is making oatmeal cookies
She wants to make 1 1/2 batches
Each batch of cookies requires 2 1/2 cups of oatmeal
She has 3 1/4 cups of oatmeal
How many more cups of oatmeal does Caitlin need?

Answers

Answer: She needs 1/2 a cup of oatmeal

Step-by-step explanation:

step 1. turn the 2 1/2 into a decimal to get 2.5

step 2. divide the decimal in half to get 1.25

step 3. add 2.5 + 1.25 = 3.75

step 4. take that answer and subtract it by how much oatmeal you have (3.25) to get 0.5       this means that you need half a cup of oatmeal to make 1 1/2 batches of oatmeal cookies

what is the solution of the system of equations below? 2a + 3b = 12 and a = 1/2b - 6

Answers

Answer:

\(a= - 3 \\ b = 6\)

Answer:

a=-3, b=6

Step-by-step explanation:

1) First, take a=1/2b-6 and plug it into 2a+3b=12

2(1/2b-6)+3b=12

2) Multiply out the 2

b-12+3b=12

3) Combine like terms

4b-12=12

4) Isolate b by adding 12 to the other side

4b=24

5) Divide by 4 so b doesn't have a variable in front

b=6

To solve for a:

You know that b=6, and a=1/2b-6 so you can plug in b to solve for a

a=1/2(6)-6

Solve the equation to get a

a=3-6

a=-3

Attached is a written explanation

Rewrite the expression c + 0.25c as a single term with a fractional coefficient.
please help (No spam) (No stu-pid answers please)

Answers

Answer:

5c/4

Step-by-step explanation:

c = c × 1

0.25c = 0.25c × 1

c + 0.25c

Take " c " common.

= c × (1 + 0.25)

= c × 1.25

Convert 1.25 into a simpler fraction

1.25

= 125/100

= 5/4

c × 1.25

= c × 5/4

= (c × 5)/4

= 5c/4

The fractional coefficient is (5c/4)

What is a coefficient?

A coefficient is a number or any symbol representing a constant value that is multiplied by the variable of a single term

Given:

\(\sf c+0.25c\)

\(\sf =(1+0.25)c\)

\(\sf =(1.25)(c)\)

\(\sf =1.25c\)

\(\sf =\dfrac{125}{100}\)

\(\sf =\dfrac{5}{4}\)

\(\sf =\dfrac{5c}{4}\)

Hence the fractional coefficient is (5c/4)

Mrs. Jones wants to paint the back wall of her classroom light blue. If the dimensions of the wall is 20 feet by 12 feet, how much paint will she need to paint her classroom wall? Round to the nearest tenth if necessary.

Answers

Answer:

The total area of the back classroom wall is (20ft x 12ft) = 240ft²

The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².

Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.

Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

The answer to the question is 0.6 gallons

What is the percentage?

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

Your fitness tracker overestimates the number of steps you take by 5%. The trackers indicate that you took 7350 steps today.

Let x be the actual number of steps. Then the equation will be given as,

(1 + 0.05)x = 7350

x = 7350 / 1.05

x = 7,000

The actual number of steps you took today will be

(1 + 0.05)x = 7350

x = 7350 / 1.05

x = 7,000

The commission paid on the merchandise sold last month is $810.

The term commission refers to the money that a salesman is paid after making sales. It is the portion of the profit that is given to a salesman after making sales.

If the total merchandise sold = $9000

Amount given as commission = 9% of all sales

Hence commission paid = 9/100 × $9000 = $810

You have to subtract 3x + 18 from 5x - 12:

=> 5x - 12 - ( 3x + 18) = 5x - 12 - 3x - 18 = 5x - 3x - 12 - 18 = 2x - 30

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?

Answers

To determine whether Keira's statement is correct, we need to analyze the information provided.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.

If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.

However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
in order to know if Keira has two tickets left, we need to know the first number of tickets without that number there is no way to find the remainder

Polygon JKLM is drawn with vertices J(−4, −3), K(−4, −6), L(−1, −6), M(−1, −3). Determine the image coordinates of L′ if the pre-image is reflected across y = −3.

L′(−3, 6)
L′(−1, 6)
L′(−1, 0)
L′(1, 0)

Answers

To reflect the pre-image across y = -3, we need to flip the entire polygon over the line y = -3. This means that the x-coordinates of each point will remain the same, but the y-coordinates will be reflected across the line.The y-coordinate of point L is -6, which is 3 units below the line y = -3. When reflected, this point will be 3 units above the line y = -3. Therefore, the image coordinates of L' will be (−1, 0), since the x-coordinate of L is -1 and the y-coordinate of L' is 3 units above y = -3, which is 0.So, the image coordinates of L' are (−1, 0).

How to define a linear function?

The slope-intercept representation of a linear function is given by the equation presented as follows:

y = mx + b

The coefficients of the function and their meaning are described as follows:

m is the slope of the function, representing the change in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, which is the initial value of the function, i.e., the numeric value of the function when the input variable x assumes a value of 0. On a graph, it is the value of y when the graph of the function crosses the y-axis.

The slope and the intercept for the function in this problem are given as follows:

Slope of -1.22, meaning that for an increase of one degree Fahrenheit, the predicted decrease in the cost is of $1.22.Intercept of 96.2, meaning that the predicted heating cost for a month with temperature of 0 ºF is of $96.20.

Hence, the predicted cost for a month with temperature of 25ºF is given as follows:

y = -1.22(25) + 96.20 = $65.70.
