Answer:
- 10 - (-20 + 5)
Step-by-step explanation:
- 10 - (-20 + 5)
- 10 - (-15) = -10 + 15

have a nice day and mark me brainliest! :)
Answer:

Step-by-step explanation:
Given
Parallel lines A and B
Required
Find x
For A and B to be parallel, then 5x + 9 and 6x - 2 are alternate interior angles
And alternate interior angles are always equal
This means that

Collect like terms


Multiply both sides by -1


The maximum number of turning points in a cubic function is 2.
In this case,

The discriminant is

, which means the derivative has no real roots. This means there are no critical points and thus no turning points/relative extrema.
