R + c=24
r=3c
3c+c=24
x=6
So there are 18 rock CDs
Answer:
Part 1: or
Part 2:
Step-by-step explanation:
To start things off, you must put everything on the opposite side of y so that you only have the y variable left.
In this case, put x onto the other side, making it negative since it's flipped, so you get (since the x is negative you're using subtraction from 11).
Next, divide both sides by 5 to make 5y into y:
Then in this case you turn y=f(x), but the system did it for you, so all you have to put is .
For the second part you must replace x with 2 since you need to find f(2).
Your answer for part 2 is .
The total cost that company ABC uses to produce x graphing calculators in a month is given by y = 1.5x + 150
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The standard form of a linear function is:
y = mx + b
Where m is the rate of change and b is the initial value of y.
Let y represent the total cost of producing x calculators in a month, hence:
y = 1.5x + 150
The total cost that company ABC uses to produce x graphing calculators in a month is given by y = 1.5x + 150
