Ieda and Thanh both offer piano lessons. Ieda charges an initial fee of $8.50 and an hourly rate of $11.00. Thanh charges an ini
Verizon [17]

Answer:

after 3 hours of instruction.

Step-by-step explanation:

First, start by setting up the equation.

Leda charges an initial fee, meaning this fee is only going to be one time. However, there is an hourly rate of 11. Since we do not know how many hours these piano lessons are going to last, we put a variable (I will use x), after this number.

The initial fee is 8.50. There needs to be a variable after 11 because that is the number we don't know.

The equation for Leda's lessons are <em>8.50+11.00x. </em>

Now, we need to find out what the equation for Thanh's lessons are going to be, because we're going to be setting both equations equal to each other to find out when they cost the same. At the moment both equal each other, is when they are the same amount.

Thanh's equation also has an intial fee and an hourly rate. So, the equation will be

<em>10.00+10.50x. </em>

Now we solve.

<em>8.50+11.00x = 10.00+10.50x </em>

First, subtract from both sides. We will do the numbers without variables first.

<em>8.50+11.00x = 10.00+10.50x </em>

<em>-8.50               -8.50 </em>

<em>____________________</em>

<em>0     +11.00x =   1.50 +10.50x</em>

Then, subtract the x's. (taking away the zero because it is equivalent to nothing)

<em>11.00x =   1.50 +10.50x</em>

<em>- 10.50x            -10.50x</em>

<em>__________________</em>

<em>0.50x = 1.50 </em>

Lastly, to find out the answer, we divide.

1.50/0.50= 3.

<u>To check your answer, you can plug into the original equation. </u>

<em>8.50+11.00 times 3 = 10.00+10.50 times 3 </em>

Both sides equal 41.50, meaning they are equal to each other!

Caleb made the table below to show the number of hours he works and the amounts he earns over a four-week period. Caleb’s Earnin
Ganezh [65]
<h2>Answer:</h2>

The ratios of earnings to hours are not the same each week, so the earnings do not vary directly with the hours.

<h2>Step-by-step explanation:</h2>

We know that the data points given by (x,y) are in direct variation if:

\dfrac{y}{x}=k  for each (x,y)

We are given data as:

Caleb’s Earnings Hours(x)        12          15         18         21

Earnings (in dollars)(y)              140        170      200     230

So, we could see the ratio as:

  • \dfrac{140}{12}=\dfrac{35}{3}
  • \dfrac{170}{15}=\dfrac{34}{3}
  • \dfrac{200}{18}=\dfrac{100}{9}
  • \dfrac{230}{21}

Hence, we could see that each ratio are not equal.

Hence, the relationship between the earnings and the number of hours does not represents a direct variation.

madam [21]

Answer:

Choices are missing here.

However, we can find the plot that represents the data.

To draw a scatterplot, we just need to draw points, where the indepedent variable is going to be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, that is the position of each player.

So, all points we need to draw the plot are:

(1, 28)

(2, 13)

(3, 4)

(4, 8)

(5, 15)

(6, 10)

(7, 22)

(8, 7)

(9, 11)

(10, 15)

The image attached shows the plot that represents this data set.
