I used cymath.com. I highly recommend it. It shows you the steps to the problem you want to solve!
I hope this helps! :)
The last step is to solve for z
THE ANSWER IS..... X1= -6 & X2=0
I believe the answer is 0.273
Y2-y1
x2-x1
(formula to use)
Explanation: (x,y) so
4=x1
0=y1
-1= x2
1=y2
1-0 over -1-4
1/-5
1/-5 is the slope
The money was paid at an annual interest of 261.42%
Explanation:
- The initial amount of the guitar when it was loaned was $960. After a month the guitar cost $1,170. This means that in one month the price went from $960 to $1,170. Increase in cost = Difference between two costs = $1,170 - $960 = $210.
- To convert this into a percent we divide the difference in value by the original price and multiply the answer with 100 to convert it into a percentage. % increase in cost = difference between two costs / original cost % increase in cost = ($210 / $960) * 100 = 0.21785 * 100 = 21.785%
- This 21.875% was the monthly interest that was paid. To convert it into annual interest rate we multiply it with the 12 months.
- Annual interest rate = monthly interest rate * 12 = 21.785% * 12 = 261.42%. This means if the guitar was loaned for a year, you would have to pay $3469.44.
