Answer:
Step-by-step explanation:
<u><em>
Options are:
</em></u>
- <em>2 feet
</em>
- <em>3 feet
</em>
- <em>9 feet
</em>
- <em>15 feet
</em>
- <em>19 feet
</em>
- <em>21 feet
</em>
- <em>30 feet</em>
<em>-------------------------------------</em>
Use the triangle inequality theorem: sum of any two side must be greater than the third side by length
- 2 feet ⇒ no, as 2 + 9 < 12
- 3 feet ⇒ no, as 3 + 9 = 12
- 9 feet ⇒ yes
- 15 feet ⇒ yes
- 19 feet ⇒ yes
- 21 feet ⇒ no, as 9 + 12 = 21
- 30 feet ⇒ no, as 9 + 12 < 30

Answer:
Slope m = -5/8
Step-by-step explanation:
5x + 8y = 16
Making y as subject of formula
8y = -5x + 16
Dividing each term by 8
8y/8 = -5x/8 + 16/8
y = -5x/8 + 2
Comparing with y = mx + c
Where m = slope and c the y intercept
Slope m = -5/8
