You can buy 6 lbs of apples for 9$ because 3*3=9, and 2*3=6 and it maintains a constant rate of change(random term that doesn't really apply but still works)9lb=144 oz...144 divided by 5 is 28 apples with change left over.
.
To identify the rate of change (or unit rate) I would usually look for a pattern in the table or graph. For example, if I got a problem like what is the unit rate for price per pound of potatoes and they gave me a chart like this:
Price. Potatoes
1. 3
2. 6
3. 9
I could determine that the unit rate (or rate of change) would be that for every $1 you could get 3 potatoes
I hope this helped! Have a wonderful day! :-)

Answer: D
Step-by-step explanation:
Given that Svana wants to solve the equation 1/2x - 1.0675 = 3x - 4145.
This equation is a system of equations which can be solved by using simultaneous equation methods.
But if she uses a graphing program to graph the equations y = 1/2x - 1.0675 and y = 3x - 4.145
The solution of 1/2x - 1.0675 = 3x - 4.145. Will be the point of intersection of the two equation.
Trace the point of intersection to the x - axis and also to the y - axis.
The solution to the system of equations is ( 1.231, - 0.452 )
