I am assuming you want to find the simplest form of the inequality.
1.

2.

3.

1. Start
2. Subtract 9 from each side
3. Divide both sides by 3
Answer:
the answer is 0.012, terminating
Step-by-step explanation:
move the decimal place three places to the left
since it is not repeating it is terminating
Answer:
x³ - 8x² - 20x
Step-by-step explanation:
Zeroes: 10, 0, -2
Factors are: (x - 10), (x - 0), (x + 2)
Multiply all factors to get expression:
(x - 10)x(x + 2) = x(x - 10)(x + 2)
= x(x² - 10x + 2x - 20)
= x(x² - 8x - 20)
= x³ - 8x² - 20x
Answer:
1-8 = -7
Step-by-step explanation:
1 - 8
1 0 -1 -2 -3 -4 -5 -6 -7
I'd suggest you begin by subtracting 4 / (x-4) from both sides. Doing that would leave you with 1 / (x-4) - 2 / (x+2) = 0.
LCD is (x-4)(x+2). Mult. all three terms by (x-4)(x+2). The resulting equation is
x+2 - 2(x-4) = 0. Then x+2 = 2x - 8 => x = 10
Subst. 10 for x in the original equation to verify that 10 is indeed a solution.
