Answer:
1200 inches
Step-by-step explanation:
Given that:
Scale used by Anna in her drawings = 1 : 600
Length of drawing made by Anna of a building = 6 inches
Scale used by Greg in the drawing = 1 : 300
To find:
The length of scale drawing made by Greg.
Solution:
Here, we first need to find the original length of the building so that we can find the length of scale drawing made by Greg.
Ratio 1 : 600 means 600 is the actual length of building, if the length of scale drawing is 1.
Here, we are given length of scale drawing as 6 inches, therefore the actual length of building = 6 600 = 3600 inches
Now, applying the ratio 1 : 300, we get the length of scale drawing by Greg as = <em>1200 inches</em>

Its always best to factorise where you can, in most questions it tends to be a necessary step and even if its not, it usually makes things easier;
In this case, you can factorise the denominator:
To get y-intercept/s, set x = 0 and solve:
y-intercept: (0, 1/12)
To get x-intercept/s, set y = 0 and solve:
x-intercept: (1, 0)
To find the asymptotes, it is necessary for us to have factorised the denominator so its a good thing that I did so at the beginning;
To get the vertical asymptote/s, set the denominator equal to 0, then just rearrange to get x:
vertical asymptotes: x = 4 and x = -3
There are no horizontal asymptotes.
