Answer:
A number is odd
Step-by-step explanation:
First we will do -3 times everything in the parenthesis.
-3 times -4n = 12n
-3 times 30 = -90
SO,
12n - 90 = -30
+90 +90
12n = 60
divide 12 on both sides;
n = 5
This is your answer,

Answer: The constant proportionality is 5/4
Step-by-step explanation: The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.
Since y=k, there is a slope of zero, which is just a horizontal line k units from the x-axis. In this case k=-5, so the graph of y=-5 is a horizontal line 5 units below the x-axis...
