Answer:
f⁻¹(x) = (4x)/5
Step-by-step explanation:
f(x) = 2x - 3x/4.
Assume y=f(x). Therefore:
y = 2x - 3x/4.
Make x the subject in the above equation.
y = (2x(4) - 3x)/4.
y = 5x/4.
4y = 5x.
(4y)/5 = x.
x = (4y)/5.
Therefore:
f(y) = (4y)/5.
Replace y with x.
f⁻¹(x) = (4x)/5.
Therefore, the inverse of f(x) = 2x - 3x/4 is f⁻¹(x) = (4x)/5!!!
He needs to score a 94 on the test to average 85% on all tests.
75+68+92+100+94=429 429/5=85.8
It's 4:3 because it's divided by 6
$180 for 6 months
Why: Well the equation is " y = 25x + 30 " where x represents the months. First you do 25 x 6 because the equation says $25 PER MONTH. After that, add the initial fee of $30 giving you the total of $180.
