Hello,
The inverse of the function is f^-1(X)=-3-x
How?
f (x)=-x-3
replace f(X) with y
y=-x-3
interchange the variables
x=-y-3
solve for y and replace f^-1 (X)
Hope this helps
Answer:
The particle's velocity is the derivative of the particle's position. The particles's acceleration is the derivative of the particle's velocity. You can compute the velocity and acceleration as follows:
Step-by-step explanation:
The velocity at is .
The speed at t=0 is . Then, the velocity at t=0 written as a product of the speed at t=0 and the direction at t=0 is
Simple...
you have: 18-7x= -20.5
Isolate the variable x
18-7x= -20.5
18-7x= -20.5
-18 -18
-7x=-38.5
Now simply divide-->>
x=5.5
Thus, your answer.
Answer:
mx is the slope. b is the y-intercept
Step-by-step explanation:
the first thing you should always do is identify your slope this is key for graphing. remember your slope is b so what ever b is you locate that point in the x axis.
then whatever your slope is remember that it is rise over run so say your equation is y=3x+5 you plot the point on the y intercept which is 5. now 3x is your slope so you put it as a fraction to make it easier this is what it looks like in a fraction "3/1" so you go up 3 on the graph and over 1 because of rise/run
Finding a common denominator between 10 and 12 to be 10*12=120, we can multiply 9/10 by 12/12 and 3/12 by 10/10 to get 108/120 and 30/120 respectively. Dividing the 2 (as we want to know how much 3/12 or 30/120 goes into 9/10 or 108/120), we get
(108/120)/(30/120)=(108/120)*(120/30)=(108/30)=3+18/30 (as 30 goes into 90 3 times and 108-90=18)
