:in order to solve the inequality - x > 8, which of the following steps must be done? divide by -4 and keep the inequality symbol divide by -4 and flip the inequality symbol multiply by -4 and keep the inequality symbol multiply by -4 and flip the inequality symbol

-12

Step-by-step explanation:

x/4 - 5= -8

Add 5 to each side

x/4 -5+5 = -8+5

x/4 = -3

Multiply each side by 4

x/4*4 = -3*4

x = -12

Hey there! :)

We're trying to get "x" onto its own side of the equal sign, so let's start out by adding 5 to both sides of the equal sign.

x/4 -5 + 5 = -8 + 5

Simplify.

x/4 = -3

Now, we need to get rid of "4" as the denominator (the bottom number in a fraction). So to do so, we must multiply both sides by 4.

x/4 · 4 = -3 · 4

Simplify.

x = -12

So, our answer is your second answer choice : -12

x = +- 2 and x = +- √2

Step-by-step explanation:

Let's covert x^4 - 6x^2 + 8 = 0 into quadratic equation.

Let e = x ^ 2

So,

(x^2)^2 - 6x^2 + 8 = 0

e^2 - 6e + 8 = 0

e^2 - 4e - 2e + 8 = 0

e( e - 4 ) -2( e - 4 )

( e - 4 ) ( e - 2 ) = 0

Either,

e - 4 = 0

x^2 - 4 = 0 ( REMEMBER THAT e= x^2)

x^2 = 4

x = +- 2

Or,

e - 2 = 0

x^2 = 2

x = +- √2

x=40

Step-by-step explanation:

x/4 - x/8

LCM of 4,8=8

x/4x2/2 - x/8=5

2x/8 - x/8 =5

x/8=5

transpose

x=5x8

x=40
