So firstly, subtract x on both sides:
Next, divide -2 on both sides, and your answer will be y = 1/2x - 3/2 , or the last option.

Answer:
The total earning of commission on sales of 85, 000 will be:
Step-by-step explanation:
- Total sales earning = 85,000
As salesperson earns 5% commission the first 70,000.
As the salesperson earns 7% commission on the sales over 70,000.
As 15000 is the sales earning on which he will get commission 7%.
Because
- 85,000 - 70,000 = 15000
So the 7% earning of salesperson will on 15000 will be:
Therefore, the total earning of commission on sales of 85, 000 will be:
Answer:
-600
Step-by-step explanation:
The rate of change of a function f(x) in a certain interval is the ratio between the change of the function and the change in the value of x:
The rate of change of a function tells how much the value of the function is changing per change in unit of x: therefore, for a linear function it corresponds to the slope of the line.
In this problem, the function f(x) is equal to the value of the business machine in dollars, while the variable x represents the number of years.
Here we are told that the machine was purchased for
while its value decreases by $600 each year, so
This means that the linear function that represents the value of the machine after x years is:
Therefore, the rate of change of the function is -600.
