Since they only give you the y values in the table, it would be easier if you isolated the x in the rule:
y = x/4
Multiply both sides by 4
4y = x
Now you can simply substitute the y values into the rule to get the x
4(4) = 16
4(2) = 8
4(9) = 36
~~hope this helps~~
16 × 35 = 560
560 + 960 = 1,520
1,520 / 19 = 80
80 / 16 = 5
Answer = 5
Hope this helped☺☺
Principal, P = 2400
interest rate, i = 4% (=0.04)
number of years, n=4
Simple interest,
I = Pin
=2400*0.04*4
=$384 after 4 years.
It'd go down 6 and right 4
Pi radians = 180 degrees

The answer is: 3.491 radians to 3 dp.
