Answer:
Part A: x = 4.
Part B: The answer normally would be x = 12, but since your question asked why it has no real solution, it is because the solution (x=12) does not make the equaion true. Why? Because the value given from the equation that should make the equation true does not relate the equation in itself; hence making it have no solution.
Answer:
0.012
Step-by-step explanation:
Linear approximation says that,
For a cube the surface area is 
.
So the side is 1.0 inch in, the surface area is 
square inches.
In Linear approximation means you ignore the term 
, if 
is a small number, because then will be a very smalle number and that does not contribute much to the error.
So the surface area is approximately,
So here, 
The error in the area is approximately,
So the error is 0.012.
Use the coordinates of the two black dots:
(2,3) and (7,6)
Slope is the change in Y over the change in X:
Slope = (6-3) / (7-2)
Slope = 3/5
The answer is true, the inverse of f(x) IS a function !
