Which of the following sets represents the relation f:x→2x+3? A {(0,3), (1, 6), (2, 9), (3, 12)}
B {(0,3), (1,5), (2, 6), (3, 8)}
C {(0,3), (1, 4), (2, 5), (3, 6)}
D{(0, 3), (1, 5), (2, 7), (3,9)}

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)

correct answer is b. 27/8
