How do you graph

- x \geq 20

on the coordinate plane?

https://socratic.org/questions/how-do-you-graph-x-20-on-the-coordinate-plane

See a solution process below: Explanation: First solve for

x

by multiplying each side of the inequality by

(- 1)

. However, because we are ...

Finding an antiderivative

https://math.stackexchange.com/questions/1797857/finding-an-antiderivative

x = cos 2 y ⟹ 0 \leq 2 y \leq π

\frac{1 - x}{1 + x} = tan y

⟹ 2 arctan \frac{1 - x}{1 + x} = 2 y = arccos x = \frac{π}{2} - arcsin x

But why don't we try with

\frac{1 - x}{1 + x} = u ⟹ x = \frac{1 - u ^{2}}{1 + u ^{2}}

Determine the intervals in which the following inequality is satisfied:

∣ 1 - x ∣ - x \geq 0

https://math.stackexchange.com/questions/2082512/determine-the-intervals-in-which-the-following-inequality-is-satisfied-1-x-x

x \geq 1

∣ 1 - x ∣ = x - 1 \geq x

and there is no solution. When

x \leq 1

∣ 1 - x ∣ = 1 - x \geq x

1 \geq 2 x

1 / 2 \geq x

Why not the domain is just

(- \infty, - 3)

2 - x - \frac{1}{9 - x ^{2}}

https://math.stackexchange.com/questions/2792483/why-not-the-domain-is-just-infty-3-of-sqrt2-x-frac19-x2

The fraction is defined if and only if

9 - x^{2} \neq = 0 \Leftrightarrow x \neq = \pm 3 .

However, you have done the square root part correctly:

2 - x

is defined if and only if

x \leq 2

. Because of this, we ...

How to solve Absolute Value Inequality: |x-1| ≥ 3-x

https://math.stackexchange.com/questions/874964/how-to-solve-absolute-value-inequality-x-1-%E2%89%A5-3-x

Solve two separate cases. Case 1:

x \geq 1

x - 1 \geq 3 - x

x \geq 2

x < 1

1 - x \geq 3 - x

which is never true. Hence the solution is

x \geq 2
