If (x) = 4х – 6, what is f(6)?
а. 18
b. 3
c. 4
d. 32

A

Step-by-step explanation:

Plug in 6 for x and solve

4*6= 24

24-6= 18

understand that i don't know the answers

will someone answer his question

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
