Answer: there is no solution
Step-by-step explanation: 1/4z — 13 is not the same as 1/4 + 13
Say z = 1 that would simplify as -12 3/4 = 13 1/4 they are not the same so there is no solution

Answer:
Domain is all real numbers.
Step-by-step explanation:
Given:
The function is given as:
A function is like a machine which gives an output for a given output.
The input to a function is called its domain. The domain is the set of all possible values for which the function is defined. The domain is represented by the independent variable 'x'.
The output of the function is the function value for the given 'x'. It is represented by 'y' or 'f(x)'.
So, the domain must include only those values which give a definite value for .
Here, the given function is a cubic function. A cubic function is one which has the highest power of 'x' as 3. A cubic function is defined for all real values of 'x'.
Therefore, the domain of the given function is all real values.
Answer:
1 3/5 miles/hr
Step-by-step explanation:
Let C be the speed of the current
Let D be the distance between Chan's house and the park
We know that Distance, D, is = Speed x Time
-----
Chan's speed going upstream is (8 - C)mph.
That gives us:
D = (8-C)(3 hr)
Chan's speed going downstream is (8+C)mph
So we have:
D = (8+C)(2 hr)
We know that the d is the same for these two equations, so:
(8-C)(3 hr) = (8+C)(2 hr)
24 - 3C = 16 + 2C
5C = 8
C = (8/5) or 1 3/5 mph
