To find the cost of one CD, we divide 38.04 by 4
38.04 ÷ 4 = 9.51
The answer is reasonable because it's an accurate answer.
For this case we have that by definition, the point-slope equation of a line is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have two points:

We found the slope:

Thus, the equation is of the form:

We substitute one of the points and find "b":

Finally, the equation is:

Answer:

<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>To subtract fractions, we must check if the denominators of both fractions are the same.</u>
- 2/5 - 1/7
- => 2 x 7/5 x 7 - 1 x 5/7 x 5
- => 14/35 - 5/35
<u>Now, let's subtract for the result.</u>
Hence, <u>Option B is correct.</u>
Hoped this helped.

It should be 270 since 6 x 9 x 10 x 1/2= 270
