Ava's sister paid a 4.5% annual interest rate
Her sister paid $54 more than she borrowed, divide that by 3 (years till she paid)
54/3 = 18
That's $18 for every year she'd had the $400 loan out, divide it by 4 to get the percentage
18/4 = 4.5/100 = 4.5%
Answer:
(9,3)
Step-by-step explanation:
4(.25x + .5y = 3.75) → x + 2y = 15
(4x – 8y = 12) → x – 2y = 3
2x = 18
Divide both sides by 2
x = 9
Substitute x = 9 into x + 2y = 15
9 + 2y = 15
Subtract 9 from both sides
2y = 6
Divide both sides by 2
y = 3
Solution
(9, 3)

Step-by-step explanation:
there are lots of common polar curves that are bounded therefore a polar curve is not always bounded all the time. a polar curve is required to have an unbounded function (right side of r = f(θ)) to be an unbounded polar.

Hey there!
The common ratio is 5, because you multiply by 5 to get from one term to the next.
Hope this helps :)
