Step-by-step explanation:
Answer:
B
Step-by-step explanation:
we have to find for what value of x the graph exists.
1) start to see on the left
- the graph ”hasn’t a start“ so it continues to go until -oo
2) notice that the graph stops when x = 0
3) match the two informations
x≤0

First, find the scale factor by dividing the first building's real-life height by its model height.

Now, we'll write an equation to find the model height of the second building.

Here is an equation where
represents the real-life height of a building,
represents the scale factor, and
represents the model height of the same building.
Fill in the information we already know.

Divide both sides by
.


So, the model height of the second building is
inches.
Well 4 and 6 have a common multiple:12 so

Multiplicative identity, which states that anything multiplied by 1 is itself.
