Answer:
is the expression which represents the number of CDs Marcus has
Step-by-step explanation:
Given the statement: Jim has a number (n) of CDs in his collection.
⇒ Jim has a number of CDs in his collection = n
Also, it is given that Marcus has 5 less than 2 times the number of CDs Jim has.
"2 times the number of CDs Jim has" means 2n
"5 less than 2 times the number of CDs Jim has" means 2n -5
then;
Marcus has the number of CDs = 2n -5
Therefore, the expression which represents the number of CDs Marcus has ;

Answer:
The required equation is:
Step-by-step explanation:
We need to find equation from the table given
x f(x)
3 -5
7 -2
11 1
15 4
We can write equation in the form of
where m is slope and b is y-intercept.
Finding Slope
We can used the slope formula to find slope:
From the table we have:
Putting values and finding slope
So, we get slope
Now, finding y-intercept
Using the slope and point (3,-5) we can find y-intercept
The y-intercept is
So, the equation having slope and y-intercept
will be:
The required equation is:

Here's what I found:
Identify the coordinates (x₁,y₁)and(x₂,y₂). We will use the formula to calculate the slope of the line passing through the points (3,8) and (-2, 10).
Input the values into the formula. This gives us (10 - 8)/(-2 - 3).
Subtract the values in parentheses to get 2/(-5).
Simplify the fraction to get the slope of -2/5.
Check your result using the slope calculator.
To find the slope of a line we need two coordinates on the line. Any two coordinates will suffice. We are basically measuring the amount of change of the y-coordinate, often known as the rise, divided by the change of the x-coordinate, known the the run. The calculations in finding the slope are simple and involves nothing more than basic subtraction and division.
