Answer:

See the attachment

Step-by-step explanation:

The inequalities resolve to ...

x ≥ 1 or x ≤ -3

You have chosen the correct placement of the lines on the number line. The "or equal to" symbol (≥ or ≤) means the dots at -3 and +1 are filled in, indicating those numbers are part of the solution.

If the ">" or "<" symbol is used in the inequality, the dot is left open, as in the answer you selected. The open dot indicates that value is not part of the solution set.

Using what you know about angles and triangles, what is the measure of angle 6?

zvonat [6]

∠4 = 90 (verticallyopposite)
∠2 = 68 (verticallyopposite)

∠6 = ∠2 + ∠4 (exterior angles = sum of opposite angles)

∠6 = 68 + 90 = 158°

Answer: 158°

Solve x3 = 1 over 8. 1 over 2 ±1 over 2 1 over 4 ±1 over 4

cricket20 [7]

X³ = 1/8

Take the cube root of both sides.

∛x³ = ∛(1/8)

Since x³ has 3 of such x multiplying each other so we bring out 1 of the x from the cube root sign as discussed.

x = ∛((1/2)*(1/2)*(1/2))

We bring out 1 of the (1/2) out of the cube root sign as well.

x = 1/2

So the answer is the first option. 1 over 2.

I hope this helps.
