The answer is -3, you distribute 14 then you do 18+42 and combine the x values then solve
An inverse function simply produces points (y,x) for each point (x,y) of the parent function. So to find an inverse function you must solve for the independent variable and then simply sway the variable labels...
y=4x+8 so we want to solve for x, subtract 8 from both sides
y-8=4x, divide both sides by 4
(y-8)/4=x, now simply swap variable labels...
y=(x-8)/4
f^-1(x)=(x-8)/4
Answer:
Step-by-step explanation:
given that a certain test preparation course is designed to help students improve their scores on the LSAT exam. A mock exam is given at the beginning and end of the course to determine the effectiveness of the course. The following measurements are the net change in 6 students' scores on the exam after completing the course:
We find
Mean 13.66666667 = 13.7
Standard Error 1.801234145
Margin of error for 90% = 1.645*std error = 2.963
Confidence interval = Mean ±Margin of error
=(10.704, 16.630)
Sample mean = 13.7
Answer:
Answer is 1008
Step-by-step explanation:
Given,
5 small containers of capacity 16,72,12,24, and 56 litres is required to fill a big container
The volume of big container is the LCM of the 5 given containers
LCM (16,72,12,24,56) = 1008
Therefore the capacity of the bigger container is 1008 litres.
