Solve for x
so assuming that the fractions are
(9/4)-(1/*2x))=4/x then
get all x on one side
add 1/(2x) to both sides
9/4=(4/x)+(1/(2x))
make common denomators with x and 2x
common denomenator is 2x
4/x times 2/2=8/(2x)
9/4=8/(2x)+1/(2x)
add
9/4=9/(2x)
make common denomators with 4 and 2x
common denomator is 4x
9/4 times x/x=9x/(4x)
9/(2x) times 2/2=18/(4x)
9x/(4x)=18/(4x)
multiply both sides by 4x to clear fraction
9x=18
divide both sides by 9
x=2

Answer:
11.88
Step-by-step explanation:
Given:
To find:
Which table shows correct values for the function.
Solution:
Substitute x = -8 in the function:
Apply radical rule: , if n is odd.
f(-8) = 14
Substitute x = -1 in the function:
Apply radical rule: , if n is odd.
f(-8) = 10
Substitute x = 0 in the function:
f(0) = 6
Substitute x = 8 in the function:
f(8) = -2
Therefore table 3 is shows correct values for the function.
