I believe the answer is graph A.
As x increases (moving to the right), y decreases (moving down).
For direct variation:
y = kx
9 = 12k
k = 9/12 = 3/4
Answer:
6x-9
the- sign makes it a difference and the two terms are 6x and 9
Answer:
Scale = 5ft/in
Step-by-step explanation:
Given
Scale Measurement = 6in.
Actual Width = 30ft
Required
Scale Ratio.
The scale ratio can be calculated as thus:
Scale Ratio = Actual Measurements ÷ Scale Measurements
Scale Ratio = 30ft ÷ 6in
Scale Ratio = 30ft/6in
Simplify to lowest terms
Scale Ratio = 5 ft/1 in
Scale Ratio = 5ft/in
This can also be represented as follows;
Scale Ratio = 5ft : 1in
This means that 5 ft on the actual measurements is represented by 1inch on the scale.
