0.32. Because you need to find the area, as size 8*8/2 then divide by 100 to get the decimal.I hope this helps.
Answer:
4 inches
Step-by-step explanation:
Actual dimensions:
Length = 15 feet
Width = 12 feet
Scale dimensions:
Length = 5 inches
Width = x inches
Write a proportion:

You will save $15
x×0.15=5
x=33.33333
x×0.45=15
(0,-4) would map into itself because it doesn’t move.
So, you need to know that the slope stays where it is, and that the 6 is not part of the final answer, so get rid of it.
y=2x+b
Now, submit x in for x, and y in for y.
3=2(1)+b
3=2+b
1=b
Put this in for the equation missing the b,
y=2x+1
Now check it; if you put 1 in for x, does y=3?
