2x - 2 < -12 
2x < -12 + 2 add 2 to each side 
2x < -10 perform the addition on the right side 
x < -10 / 2 divide each side by 2 
x < -5 perform the division on the right side 

2x + 3 > 7 
2x > 7 - 3 subtract 3 from each side 
2x > 4 perform the subtraction on the right side
x > 4 / 2 divide each side by 2 
x > 2 perform the division on the right side 

These are just like equations, except the you have to change the direction of the sign when you multiply or divide by a negative number

(C) x < -5 or x > 2

Which equation is equivalent to<br><br> f(x) = 16x4 – 81 = 0?
Vesna [10]

Answer:

The equivalent expression is:

16x^4-81=(4x^2-9)(4x^2+9)

Step-by-step explanation:

We have been given the equation:

f(x)=16x^4-81=0

Equivalent expression can be computed by solving the expression ai its maximum.

We can factorize the given equation:

By using a^2-b^2=(a+b)(a-b)

Here, a=4x^2,b=9

Hence, we get the equation below:

16x^4-81=(4x^2-9)(4x^2+9)

Therefore, the equivalent expression is:

16x^4-81=(4x^2-9)(4x^2+9)
