Answer:
y= 3|x|+5
Step-by-step explanation:
Remember the graph for |x| is shown on the attached picture
Since the picture you show tell us that y=5 when x=0
we have something like the following y=a|x|+5, where 'a' is a constant that represents the slope of the line (whether is the line from one side of the 'y' axis or from the other), we can see that, when x=1, y=8, so we have another point
we can use the equation for slopes using points 1 (0,5) and 2 (1,8)
thus we have that 
So the answer is y= 3|x|+5
Answer:
Remember, the formula is the second value minus the first value, divided by the first value times 100.
9. 50% Increase
10. 33% Decrease
11. 200% Increase
To calculate tip, simply move the decimal place 2 to the right and multiply it by the price. For example, If you want to leave a 20% tip, multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total including tip.
12. $23.00
13. $10.50
Answer:
-9-5x
Step-by-step explanation:
they aren't the same because of the variable on 5x. You can simplify the problem to -9-5x but that's about it unless it equals something.
20/21 is the answer to your problem.
