Answer:
I can help as welllll
Step-by-step explanation:
Recall the definition of absolute value.

When
,

When
,

The derivative does not exist at
, since the one-sided limits

and

do not match.
So the derivative of
is

Now we can write this as

since

and

Explanation:
Finish the Given statement, make use of the relationships of angles and parallel lines, then finish the algebra.
__
2. m∠6 = (1/8)m∠4 . . . . Given
3. m∠6 + m∠4 = 180° . . . . 3. same-side interior angles are supplementary
4. m∠6 + 8·m∠6 = 180° . . . . 4. Substitution (from 2, above: 8·m∠6 = m∠4)
Here is the "algebra" that gets you to line 5:
4a. 9m∠6 = 180° . . . collect terms
4b. m∠6 = 20° . . . . . divide by 9
4c. m∠4 = 8·20° = 160° . . . use the same relation as in step 4
5. m∠6 = 20°, m∠4 = 160° . . . . Algebra

Answer:
x = -3
Step-by-step explanation:
-4x + 2(5x - 6) = -3x - 39
-<u>4x</u> + <u>10x</u> - 12 = -3x - 39
-4x + 10x = 6x
6x - 12 = -3x - 39
<u>+3x</u><u> _ </u><u>+3x </u>
9x - 12 = -39
<u> </u><u>+ 12</u><u> </u><u>+12</u>
<u></u>

x = -3
-30 = -30
