Full question:

A transaction is positive if there is a sale and negative when there is a return. Each time a customer uses credit card for a transaction, the credit company charges Isabel. The credit company charges 1.5% of each sale and a fee of 0.5 % for returns

Let x represent the amount of a transaction and let f(x) represent the amount Isabel is charged for the transaction. Write a function that expresses f(x)

Answer:

f(x)= 0.015(x)

f(x)= 0.005(x)

Explanation:

If Isabel makes a sale, she has a positive transaction and therefore is charged 1.5%(which is 0.015) by the credit company for the transaction. If the product is returned, it is a negative transaction and the credit company charges 0.5%(which is 0.005) for the transaction. The functions for positive and negative transactions would be different as indicated in the answer since transactions( given by x) are different- positive and negative.

Answer:

Option D

Step-by-step explanation:

She is selling tickets for $10 each, and if 1,007 people attended, that would be: $10,070 in proceeds. So, you then subtract that from the balance at the bank: -$3,200.

-$3,200 + $10,070 = $6,870 balance.

Answer:

Step-by-step explanation:

y=m₁x+b₁   ║   y=m₂x+b₂   ⇔    m₁ = m₂

{Two lines are parallel if  their slopes are equal}

Changing to slope-intercept form:

2x - 3y = 9         {subtract 2x from both sides}

-3y = -2x + 9        {divide both sides by (-3)}

y = ²/₃x - 3     ⇒    m₁=²/₃   ⇒   m₂=²/₃

The line y=²/₃x+b passes through point (6, 7) so the equation:

7 = ²/₃×6 + b  is true

7 = 4 + b

b = 3

Therefore equation in  slope-intercept form:

                                                     y = ²/₃x + 3

The equation of the line passing through the point (6, 7) parallel to the line is y = 2/3x + 3

The equation in slope - intercept form :

2x - 3y = 9

-3y = 9 - 2x

Divide both sides by - 3

y = - 3 + 2/3x

Using the points (6, 7)

7 = c + 2/3(6)

7 = c + 12/3

7 = c + 4

c = 7 - 4 = 3

c = 3

The equation of the parallel line is thus :

Answer:

20%

Step-by-step explanation:

Here, we want to calculate the percentage increase in the price of a can of green beans

Mathematically, we use the formula below;

(new price - old price)/old price * 100%

From the question;

old price = $0.50

new price = $0.60

So we have;

(0.6-0.5)/0.5 * 100%

= 0.1/0.5 * 100%

= 20%

Answer:

  32.4 feet

Step-by-step explanation:

The applicable relationship between angle and triangle lengths is ...

  Sin = Opposite/Hypotenuse

The dock height is the side of the triangle opposite the given angle. The desired length is the hypotenuse of the triangle, so we have ...

  sin(18°) = (10 ft)/s

  s = (10 ft)/sin(18°) = (10/0.30902) ft

  s ≈ 32.4 ft

The length of the rope is about 32.4 feet.

Answer: $21 and 50 cents

Step-by-step explanation:

Given:

The increase in pressure P is the linear function of the depth d.

[tex]P(d)=0.445d+14.7[/tex]

The cost of dinner is $300 and $10 per students.

To find:

The initial value and rate of change and their interpretation.

Find the cost function C where n is the number of students.

Solution:

The slope intercept form of a linear function is

[tex]f(x)=mx+b[/tex]          ...(i)

where, m is rate of change and b is y-intercept or initial value.

We have,

[tex]P(d)=0.445d+14.7[/tex]        ...(ii)

From (i) and (ii), we get

[tex]m=0.445,b=14.7[/tex]

The initial value is 14.7. It means, the pressure at sea level is 14.7 pounds psi.

Rate of change is 0.445. It means, the pressure is increasing by 0.445 pounds psi for every feet.

The cost of dinner is $300 and $10 per students.

Let C(n) be the total cost for dinner and n be the number of students.

Fixed cost = $300

Additional cost for 1 student = $10

Additional cost for n student = $10n

Now,

Total cost = Fixed cost + Additional cost

[tex]C(n)=300+10n[/tex]

Therefore, the required cost function is [tex]C(n)=300+10n[/tex].

Answer:

(-2, -4)

Step-by-step explanation:

Since both equations are equal to y, you can set them equal to each other:

[tex]\frac{3}{2}x-1=\frac{1}{2}x-3[/tex]

Next, solve for x:

[tex]\frac{3}{2}x-1=\frac{1}{2}x-3\\x-1=-3\\x=-2[/tex]

Finally, substitute the solution for x in one of the equations (or both) to find y:

[tex]y=\frac{3}{2}(-2)-1\\y=-3-1\\y=-4[/tex]

[tex]y=\frac{1}{2}(-2)-3\\y=-1-3\\y=-4[/tex]

Therefore, the solution to the system of equations is (-2, -4).

Step-by-step explanation:

Answer:

Step-by-step explanation:

This question is a bit sloppy. In higher math courses it would not be permitted. I'll give you the general rule that applies to this question -- sort of.

If you have a triangle that hast angles of 100 50 and 30

The largest side will be opposite the 100 degree angle.

The smallest side will be opposite the 30 degree angle.

So for the question, you are intended to say that CD > AB because CD is opposite a 43 degree angle and AB is opposite a 40 degree angle.

So the answer is Since 43 > 40 then CD>AB

Mean allowance of the given students is equals to $13.

" Mean is defined as the ratio of the sum of all the given number to the  total number of numbers. It is also known as average."

Formula used

Mean = [tex]\frac{Sum of all the given numbers}{Total number of numbers}[/tex]

According to the question,

Number of students = 10

Weekly allowances of each student

= $9, $11, $13, $15, $20, $10, $12, $15, $10, $15

Substitute the value in the formula of mean we get,

mean = [tex]\frac{9+11+12+13+20+2(10)+3(15)}{10}[/tex]

         [tex]= \frac{130}{10}\\ \\= 13 dollars[/tex]

Hence, mean allowance of the given students is equals to $13.
