Solve the absolute value inequality.

Alex Ar [27]

Answer: k ≤ -4 or k ≥ $\frac{4}{3}$

<u>Explanation:</u>

| 3k + 4 | ≥ 8

3k + 4 ≥ 8 or 3k + 4 ≤ -8

<u> -4</u> <u> -4 </u> <u> -4</u> <u>-4 </u>

3k ≥ 4 or 3k ≤ -12

<u>÷3 </u> <u>÷3 </u> <u> ÷3 </u> <u>÷3 </u>

k ≥ $\frac{4}{3}$ or k ≤ -4

Reducing Fractions<br> 30/90

fgiga [73]

Answer: 1/3

<u>Divide</u>

30/90÷30/30=1/3

Since we are simplifying fractions we divide the numerator and the denominator by a number the fraction can go into.

We could use 10 then divide by 3. You can also just divide by 30 and get the answer.

Let's try dividing by 10 then 3!

30/90÷10/10=3/9

3/9÷3/3=1/3

As you can see we still get 1/3 when we divide by 3. Even tho you have to divide twice you still get 1/3. That's all that matters.

10. from the question; the circle theorem obeyed is "angled formed by semi-circle"

The angle formed in a semicircle is 90 degrees, hence

$m\angle XYZ=90^{\circ}$

This gives

$m\angle YXZ\text{ + m}\angle YZX\text{ = 90}$

But

$\begin{gathered} m\angle YXZ\text{ = 2x + 8} \\ m\angle YZX\text{ = 5X - 2} \end{gathered}$

Substituting values we get

$\begin{gathered} 2x\text{ + 8 + 5x - 2 = 90} \\ 2x\text{ + 5x + 8 - 2 = 90} \\ 7x\text{ + 6 = 90} \\ 7x\text{ = 90 -6} \\ 7x\text{ = 84} \\ \text{divide both sides by 7} \\ x\text{ = }\frac{84}{7} \\ x\text{ = 12} \end{gathered}$

hence, x =12
