You basically simplify for this one,18 / ? = 9
18/2=9
So in this case, 8*2 is 16! Hope this helps!
Answer:
$4911.45
Step-by-step explanation:
To find Megan's average daily balance, we first need to assume that the billing cycle begins at January 1st.
Now we know that there are 31 days in the month of January, we will use that as our basis.
20 days x 4805 = First 20 days of the billing cycle.
11 days 4805 + 300 = 21st day of the billing cycle.
31 days in the month
So now we simply add the first 20 days and the days after the 21st day and divide it by the number of days in the month since we're looking for the average.
(20 x 4805 + 11(4805+300))/31
(20 x 4805 + 11(5105))/31
(96100 + 56155)/31
152255/31
This then gives us:
$4911.45
y = 1 - 3x goes to slope -3, y-intercept at 1
x - 3 = y goes to slope 1, y-intercept at -3
y = 3x - 1 goes to slope 3, y-intercept at -1
-x + 3 = y goes to slope -1, y-intercept at 3
