Slope = rise/run

Step-by-step explanation:

Example: (6,3) (2, 2)

Add the x's and divide by two and then add the y's and divide by two.

6 + 2 = 8

8/2 = 4

3 + 2 = 5

5/2 = 2.5

So, the slope would be 4/2.5

Answer:

Answer is: 5^ -8  *  5^4 =  5^-4

Step-by-step explanation:

To simplify : 5^ -8  *  5^4

This can also be written as :

5^ -8  *  5^4 = 1/5^8 * 5^4

or 5^ -8  *  5^4 = 5^4 / 5^8

or 5^ -8  *  5^4 = 5^(4 - 8)

or 5^ -8  *  5^4 = 5^-4

Hence we got 5^ -8  *  5^4 =  5^-4

Answer:

$4.10

Step-by-step explanation:

Subtotal = (3 pairs of socks) x (price of socks):  

Subtotal = (3 x $1.29) = $3.87  

To get the overall total, you add tax, which is 6% of the subtotal:  

6% of the subtotal = 0.06 x subtotal = 0.06 x $3.87 = $0.23  

Subtotal + tax = $3.87 + $0.23 = $4.10

Answer:

3 1/13 hours

Step-by-step explanation:

Lets create a variable:

Samantha and Kylee together (NOT the answers) = [tex]T_{SK}[/tex]

Now lets create an equation:

[tex]1/T_{SK} = 1/T_{S} +1/T_{K}[/tex]

Let's look at the time Samantha and Kylee takes to decorate the cake by themselves:

Samantha: 5 hours

Kylee: 8 hours

Let's create an equation to find the answer now:

[tex]1/T_{SK} = 1/5 + 1/8[/tex]

Note that now that's its basically algebra, change the variable to [tex]x[/tex] like this:

[tex]1/x = 1/5 +1/8[/tex]

Now let's find the LCM (Lowest Common Multiple) of 5, 8, and [tex]x[/tex] which is 40[tex]x[/tex].

[tex]40 = 8x + 5x[/tex]

[tex]40 = 13x[/tex]

[tex]13x = 40[/tex]

[tex]x = 40/13[/tex]

[tex]x[/tex] = 3 1/13 hours

Please note that the step where it swapped 13[tex]x[/tex] and 40 is only my way, it is not necessary, it's just my own comfort.

Answer:

20 years

Step-by-step explanation:

Simple interest is only interest on the original principal amount. Every year, you earn the same interest amount.

At 5% simple interest, you earn 5% of the principal each year.

In any year, you earn

5% of $500 = 5% * 500 = 0.05 * 500 = $25

Each year, you earn $25 in interest.

How many years will it take to earn a full $500 by earning $25 per year?

$500/$25 = 20

It takes 20 years to double the $500.

Answer:

Step-by-step explanation:

First, we can transform y = cos(x) to y = 3*cos(x) by stretching the graph vertically by a factor of 3. At x = 0, the y value would now be 3 * 1 = 3 instead of 1 (the stretching would cause all new y-values to be 3 times their original values for any given x).  

Now transforming y = 3*cos(x) to y = 3*cos(10*x) will stretch the graph horizontally by a factor of 10 (for any given y value, the new x value corresponding to it is 10 times the original x value).

Finally, to transform y = 3*cos(10*x) to y = 3*cos(10(x-pi)), shift the graph to the right by pi.

Answer:

x+y = 50

Step-by-step explanation:

We can find the slope of the line

m = (y2-y1)/(x2-x1)

   = (50-41)/(0-9)

   = 9/-9

   =-1

We can use the point slope form of the equation to make an equation for a line

y-y1 = m(x-x1)

y-50 = -1(x-0)

y-50 = -x

To get it in standard from, subtract y from each side

y-y-50 = -x-y

-50 = -x-y

Multiply each side by -1

50 = x+y

x+y = 50

The equation representing the relationship between the number of bus rides and the amount of bus money is  [tex]\( x + y = 50 \)[/tex]. The option (a) is correct.

The amount of bus money Shawn will have left is [tex]y[/tex].

Representing the relationship between the number of bus rides [tex]\( x \)[/tex] .

We can see that for every 9 rides, Shawn's remaining bus money decreases by $9.

This suggests that the cost of each ride is $1 (since $9 divided by 9 rides equals $1 per ride).

We know that Shawn starts with $50 and each ride costs $1.

So, after [tex]\( x \)[/tex] rides, Shawn will have spent  [tex]\( x \)[/tex] dollars.

So, the equation is :

[tex]\[ y = \text{Initial amount} - \text{Cost per ride} \times \text{Number of rides} \][/tex]

[tex]\[ y = 50 - 1 \times x \][/tex]

[tex]\[ y = 50 - x \][/tex]

This equation can be rearranged to standard form, which is [tex]\( Ax + By = C \)[/tex] , where [tex]\( A \), \( B \), and \( C[/tex]   are constants.

For our equation,[tex]\( A = -1 \), \( B = 1 \) , and \( C = 50 \)[/tex]  , so in standard form, it is :[tex]\[ -x + y = 50 \][/tex] .

We can multiply the entire equation by -1 to get :

[tex]\[ x - y = -50 \][/tex]

[tex]\[ x + y = 50 \][/tex]

This is the equation in standard form that represents the relationship between the number of bus rides, [tex]\( x \)[/tex], and the amount of bus money Shawn will have left, [tex]\( y \)[/tex].

Therefore, the correct answer is  [tex]\( x + y = 50 \)[/tex] .

The complete question is:

Answer:

$800 is the answer because you subtract 7200 from 8000 and you get 800

Final answer:

To earn an $8,000 commission at a rate of 4%, the car dealer needs to increase his total sales by $20,000, from $180,000 last month to $200,000 this month.

Explanation:

The car dealer wishes to increase his commission from $7,200 to $8,000. Since he earns a 4% commission on all cars sold, we first need to determine how much his sales were last month. To do this, we divide his commission for the last month by the commission rate:

Last month's sales = Commission / Commission rate = $7,200 / 0.04 = $180,000

To earn $8,000 this month, we need to find the total sales required:

This month's sales = Desired commission / Commission rate = $8,000 / 0.04 = $200,000

To find the increase in total sales needed, we subtract last month's sales from this month's sales target:

Required increase in sales = This month's sales - Last month's sales = $200,000 - $180,000 = $20,000

Answer: $20.5

Step-by-step explanation:

Let x  denotes the amount for total bill.

We are given that ,  Sierra left $4.50 as a tip for a waiter.

This was 18% of the bill before the tip.

We can write 18% = 0.18. [To convert percent into decimal we divide it by 100.]

Then, the tip amount = 0.18 x Total bill

[tex]\Rightarrow\ 4.5=0.18x\\\\\Rightarrow\ x=\dfrac{4.5}{0.18}=25[/tex]

So, the total bill amount = $25

Hence, her total bill before the tip= Total bill amount - Tip amount

= $25- $4.50=$20.5

Thus ,her total bill before the tip= $20.5

To find Sierra's total bill before the tip, an equation can be created where the tip amount ($4.50) is 18% of the total bill. Solving the equation provides that Sierra's total bill before the tip was $25.

To solve this problem, you want to figure out the original bill amount before the tip was added. We know that the tip amount, $4.50, represents 18% of the original bill. Therefore, we can set up an equation to find the total bill before the tip was included.

The equation is as follows: 0.18x = $4.50, where 'x' stands for the total bill before the tip. By dividing both sides of the equation by 0.18, we can find 'x' which represents the initial bill.

So, x = $4.50 / 0.18 and calculating this gives us x = $25. Therefore, Sierra's total bill before the tip was $25.

Answer:

The cost of the bench is 425 dollars.

Step-by-step explanation:

Let x represent the garden table.

Let y represent the bench.

x + y = 804

x = y - 46

Use the substitution method.

y - 46 + y = 804

2y - 46 = 804

Add 46 to both sides.

2y = 850

Divide both sides by 2.

y = 425

Answer:

The cost of the bench is 425 dollars.

so we have s(t), namely the positional equation for the particle.

now, let's recall that the derivative of s(t) will be v(t), namely the derivative of the positional equation will be the velocity, and the derivative of the velocity will be the acceleration.

s'(t) = v(t) and s''(t) = a'(t)  <--- acceleration

so we need the 2nd derivative of s(t) firstly, and then we can check for any critical values and find its extrema.

[tex]\bf s(t)=t^4-rt^3+6t^2-20\implies \stackrel{\textit{velocity}}{s'(t)=4t^3-12t^2+12t} \\\\\\ \stackrel{\textit{acceleration}}{s''(t)=12t^2-24t+12}\implies \stackrel{\textit{derivative of acceleration}}{s'''(t)=24t-24} \\\\[-0.35em] ~\dotfill\\\\ 0=24t-24\implies 24=24t\implies \cfrac{24}{24}=t\implies 1=t[/tex]

now, if we run a first-derivative test on that acceleration derivative, namely s'''(t), let's say we test s'''(0) and that gives us a negative value, and then test s'''(2) and that gives us a positive value, so the test goes like in the picture below, clearly, 1 = t is a minumum, and is between [0, 3].

s'''(0) = -24

s'''(3) =  48

so clearly the maximum happens at the s'''(3) endpoint, when t = 3.

Area = (2x+3) * (x-4)

We will use the FOIL technique  to multiply the terms.

First:  2x*x = 2x^2

Outer:  2x* -4 = -8x

Inner:  3*x = 3x

Last = 3* -4  = -12

Add the 4 terms together:  2x^2 -8x+3x -12   = 2x^2 -5x-12

Area = 2x^2 -5x-12

Answer: 2x^2 - 5x - 12

Step-by-step explanation: The correct answer is 2x^2 - 5x - 12. To find the area of a rectangle you multiply the length by the width. So you multiply (2x + 3)(x - 4) using the FOIL method.
