Answer:

C: x > -6 or x < –9

Step-by-step explanation:

x + 9 < 0 or 2x > –12

For x + 9 < 0:

Isolate x by subtracting 9 from both sides of the inequality:

x + 9 – 9 < 0 – 9

x + 0 < – 9

x < – 9

For 2x > – 12:

Isolate x by dividing both sides of the inequality by 2:

\frac{2x}{2} > \frac{-12}{2}

x > – 6

Therefore, the solution is:

x < – 9 or x > – 6

Interval notation: [(– ∞, –9) ∪ (–6, ∞)]

The answer is C: x > -6 or x < –9

If (x^2+1)/x = 7 find x^2+(1/x^2)
White raven [17]

Answer:

x²+(1/x²) = 47

Step-by-step explanation:

by identity : (a+b)² = a²+b²+2ab

(x+1/x)²= x²+(1/x)²+2(x)(1/x)

(x+1/x)²= x²+(1/x²)+2....(1)

since : (x²+1)/x = 7

(x²/x) +(1/x) = 7

x + (1/x )= 7

put the value for : x +(1/x) in (1) :

49 = x²+(1/x²)+2

x²+(1/x²) = 47
