In each of the following, a variation relationship is given. Find the requested value of the function in each. a. y = 3x when x = 2

b. y = –2⁄ x when x = 16

c. y = ––3⁄ x2 when x = –3

d. y = 14x2 when x = 100

e. y = –2x when x =.4

f. y = 6/7x2 when x= 3

a.y=6

b.-1/8

c.1/2

d.2800

e.-8

f.7.71

Step-by-step explanation:

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)
