Answer:
fill in the missing number on the number line
2350 2350
You would first Multiply both sides by 3x+7
The solution or the value of x would be -12
Answer:
L = 20 cm, W = 10cm
Step-by-step explanation:
P=2L+2W
P=60,L=2W
60 = 2(2W)+2W
60=4W+2W
60=6W
W=10
plug in L=2W
L=2x10
L=20
You can find the inverse function for
.. y = (1 +e^x)/(1 -e^x)
by swapping the variables and solving for y.
.. x = (1 +e^y)/(1 -e^y)
.. x(1 -e^y) = 1 +e^y
.. x -1 = e^y*(1 +x)
.. e^y = (x -1)/(x +1)
.. y = ln((x -1)/(x +1)) . . . . . your inverse function

The orange dashed line is there to help you see the inverse function is the original function reflected across the line y=x.
