Answer:
Step-by-step explanation:
A linear function has the following format:
In which a is the slope(rate of change) and b is the y-intercept, that is, the value of y when x = 0.
Rate of change of 3
This means that 
So
A solution at (6, 12).
This means that when x = 6, y = 12. So
The linear function is:
180 times 4/100= 7.20- Sales tax
180+7.20= $187.20 is the total cost

For this case we have the following relationship:
27:9
To find two equivalent relationships, what we must do is divide both numbers by a number that is multiple of both.
We then have to divide by three:
9:3
Then, dividing again between three we have:
3:1
Answer:
two ratios that are equivalent to 27:9 are:
Ratio 1:
9:3
Ratio 2:
3:1
Answer:
C
Step-by-step explanation:
C because you multiply the nimbers and then divid.
