12 OT 15 What is the solution to the inequality below?
2- 2x>-20
A. >12
B. x <9
C. x < 11
D. x < 10

- 2x  > -20

x  > 10

Step-by-step explanation:

Given:

2- 2x > -20

Find:

Value of inequality

Computation:

2- 2x > -20

Subtract 2 both side

- 2x  > -20

Divide -2 both side

x  > 10

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)

answer: 0.64
