6. Write the inequality using interval notation for the graph.
makkiz [27]

Answer:

C

Step-by-step explanation:

C is the correct answer because it represents exactly what the graph shows with the bold lines.

As you can see in the graph, there is no interception between 7 and 12. Therfore, the answer can't be B(because it represents the area between the two numbers).

A isn't the correct answer either because it represents a dot, which is obviously not the case here since there is no dot.

I can't explain why C isn't the right answer, but I hope that explanation that I gave is enough for you to understand ;)

(If you have any questions about the way I solved it, don't hesitate to ask me in the comments, and if you find my answer helpful - consider marking it Brainliest ÷) )

vredina [299]
It will take an additional 8 weeks to reach a height of 48 centimeters.

y = 4.5x

Since, the maximum height is 48 cm and the plant has already grown 12 cm, we deduct the 12 from 48 to get the additional weeks it needs to grow.

48 - 12 = 4.5x
36 = 4.5x
36/4.5 = 4.5x / 4.5
x = 8 weeks.
