Two domestic courier services charge as per the functions y = 4x + 1 and y = 3x + 2, where x represents the weight of the parcel in pounds and y represents the total cost of the parcel. For what weight is the total cost the same in both services?
A .3 pounds B .2 pounds C .1 pound D. 0.5 pound

Answer:

y = 70x + 35

Step-by-step explanation:

$75 - $5 = $70 (this is the amount charged minus the amount needed to get the job done per car wash)

the +35 is the tips extra/ constant that will be added after the jobs are done.

x is the amount of car washes done

y would be the profit received.

thus y = 70x + 35 (profit = value of car wash * number of cars washed + tips)

Answer:

Step-by-step explanation:

Profit = Income less outgo

         = (car wash income + tips) - (supplies)

$250 = ($75n + $35) - ($5n), or

$215  = $70n     (where n represents the number of cars washed)

This comes out to n = $215/$70, or approximately 3 car washes.

Answer:

25

Step-by-step explanation:

4a +12 -2c + c

4( ) + 12 - 2( ) + ( )

4(4) + 12 - 2(3) + 3

16 + 12 - 6 + 3

28 - 6 + 3

22 + 3

25

Helping in the name of Jesus.

Therefore,  4a  +   12   -   2c   +   c  =   25

       a  =   4  

       c  =   3

        4a  +   12   -   2c   +   c

       (4)(4)  +  12  -     (2)(3)   +    3

         16     +   12   -   (2)(3)   +    3

         28      -            (2)(3)    +    3

         28     -   6     +     3

         22    +      3   =   25

Draw a conclusion:

     4a  +   12   -   2c   +   c   =  25

Answer:

6 inches

Step-by-step explanation:

1 yard =36 inches

36 inches< 42 inches

42-36 inches = 6 inches

Answer:

.1666676

Step-by-step explanation:

1 in = 0.0277778 yard

42  × 0.0277778 = 1.1666676

1.1666676 - 1 = .1666676

so 42 inches is .1666676 greater than 1 yard

Answer:

\(f^{-1}\left(f(576)\right)=\boxed{576}\)

\(f^{-1}(-7)+f(-7)=\boxed{13}\)

Step-by-step explanation:

The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).

Given table:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)

Inverse function:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)

If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).

Therefore:

\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)

The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.

The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.

Therefore:

\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)

Answer:

This example represents discrete data.

Step-by-step explanation:

Discrete data refers to information that can only take certain specific values. In this case, the number of pamphlets added to the box (x) can only take on integer values such as 0, 1, 2, 3. Similarly, the effect on the box's weight (y) is also given as specific values: 0, 6, 12, 18.

In contrast, continuous data would involve measurements that can take any value within a range, such as height, weight, or temperature.

Since the number of pamphlets added and the corresponding effect on the box's weight are presented as specific, separate values, the data in this example is considered discrete.

Answer:

  x = 1

Step-by-step explanation:

You want the solution to the multi-step equation -5 -(15x -1) = 2(7x -16) -x.

It is often useful to simplify the equation first. Doing that gives ...

  -5 -15x +1 = 14x -32 -x . . . . . . eliminate parentheses

  -15x -4 = 13x -32 . . . . . . . . collect terms

  28 = 28x . . . . . . . . . . . . add 15x+32

  1 = x . . . . . . . . . . . . . divide by 28

Additional comment

The "inverse operations" used here are addition of 15x to cancel the subtraction of 15x, and addition of 32 to cancel the subtraction of 32. The inverse of subtraction is addition.

Hey! Let's help you with your question here!

So, let's start with what we are trying to find and that's the unit rate price per ounce of a large box of cereal. Now, let's focus on what we're given.

Alright! We've figured out what we know and what we need to find! Now, we can start figuring out how to solve it! Now how do we do that? Well in order to figure out the unit rate price, we need to take the price and divide it by the total quantity. In a formula, it looks like this:

\(Unit Rate=\frac{cost}{quantity}\)

If we plug everything into the formula, it would look like this:

\(UnitRate=\frac{5.20}{26}\)

\(UnitRate=0.20\)

Therefore, we can conclude that the unit rate price per ounce for the large box of cereal is $0.20 per ounce.

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Answer:

32 degrees

Step-by-step explanation:

The sum of all angles in a triangle is 180 degrees.

A right angle (The one marked by a small square on the bottom left) measures 90 degrees.

You're given that the other two angles in the triangle measure 58 and x degrees.

To find x, we'll find the sum of all angles, and equate it to 180.

The sum of all angles = 90 + 58 + x = 148 + x degrees

\(148 + x = 180 \text{ // -148}\\\cancel{148 -148} + x = 180 - 148\\x = 32^{\circ}\)

Answer:

60 yards.

Step-by-step explanation:

We can use the concept of proportional relationships to find the width of the field for 11-14 year-old players.

The ratio of length to width of the field for 9 and 10 year-old players is:

75 yards : 45 yards

We can simplify this ratio by dividing both sides by 15:

5 yards : 3 yards

This means that for every 5 yards in length, the field is 3 yards wide.

Now we can use this ratio to find the width of the field for 11-14 year-old players:

Ratio of length to width for 11-14 year-old players:

100 yards : w yards

where w is the unknown width.

We can set up a proportion using the ratio we found for the 9 and 10 year-old players:

5 yards : 3 yards = 100 yards : w yards

To solve for w, we can cross-multiply:

5 yards x w yards = 3 yards x 100 yards

5w = 300

w = 60

Therefore, the width of the field for 11-14 year-old players is 60 yards.
