Lets review the options one by one:
X A.) The question says the y must be <u>less than</u> 100, not less than or equal to.
X B.) The y becomes 0, but 0 is neutral, not a positive number.
X C.) The height must be positive at all times, according to the range given.
√ D.) The given graph contains a max with a positive number under 100.
Therefore, the correct answer choice would be Option D (4).

Answer:
31
Step-by-step explanation:
f(-9) = -(-9)-5
= 9-5
= 4
f(-9) - 9(-3) = 4 - (-27)
= 31

Answer:</h3>
- interior: 144°
- exterior: 36°
<h3>
Step-by-step explanation:</h3>
It may be easiest to remember that the sum of exterior angles of any convex polygon is always 360°.
Your decagon has a sum of exterior angles that is 360°. Since it is a regular 10-sided polygon, each one is 1/10 that value: 36°.
The measure of each exterior angle is 36°.
The measure of an interior angle is the supplement of the exterior angle. Each interior angle of the regular 10-sided polygon will be ...
... 180° -36° = 144°
The measure of each interior angle is 144°.
_____
A formula often used for the sum of the measures of the interior angles is ...
... interior angle total = (n -2)×180°
For a 10-sided figure, the interior angle total is ...
... (10 -2)×180° = 1440°
When this sum is divided into 10 equal angles, the measure of one interior angle is ...
... 1440°/10 = 144° . . . . . agrees with the above computation
The exterior angle measure is the supplement of this:
... 180° -144° = 36° . . . . . exterior angle measure; agrees with the above computation
1. 2
2. The Y axis
3. 3 rights and 1 down (3, -1)
