Plotting the data to get the line of best fit, it is:
y<span> = 0.087</span>x<span> + 0.587
substitute x=2030-1980=50,
y = $4.94 is the price in 2030</span>
2-3k because the difference between something means it is subtraction and the product of 3 and k would just be 3k since you don't know what k is.
4^3 = 64
log4 64 = 3
The exponent always comes to the other side.
Answer: 
Step-by-step explanation:
To solve for y, we want to isolate y.
[multiply both sides by y]
[subtract both sides by 3y]
[factor out y]
[divide both sides by (w-3)]

Now, we know that
.
Note that both sides were multiplied by 5.
So that would be "Multiplication Property of Equality."
Basically, this property states that if a=b, then ac = bc.
