Same as the other one
part A)
CD 12,000 at 6%, how much is that? (6/100) * 12000
CB 4000 at 5%, how much is that? (5/100) * 4000
part B)
total investment was 12000 + 4000 = 16000
the earned interest above are 720 and 200 respectively
total yield was, 720 + 200 = 920
if 16000 is the 100%, how much is 920 in percentage?

solve for "x"
The inverse of the given function is y = √5x + 7/2 - 3
<h3>Inverse of a function</h3>
Given the function expressed below;
5y + 4 = (x+3)² +1/2
5y = (x+3)² - 7/2
y = 1/5(x+3)² - 7/10
Replace y as x
x = 1/5(y+3)² - 7/10
Make y the subject of the formula
5x = (y+3)²- 7/2
(y+3)² = 5x + 7/2
y+3 = √5x + 7/2
y = √5x + 7/2 - 3
Hence the inverse of the given function is y = √5x + 7/2 - 3
