Answer:

The constant of proportionality is 0.3, or K=0.3.

Step-by-step explanation:
The chart I attached shows points that are plotted on the proportional line. In order to find the constant of proportionality from these points, you have to divide the amount of change by the number of years. For example, 3 divided by 10 or 6 divided by 20. This results in 0.3, which means that every year, there is 0.3 centimeters of change in the sea level.

-4 + 3y = -43<br> what does y equal?
NeTakaya

Answer:

-13

Step-by-step explanation:

We remove the -4 by adding 4 to each side:

3y = -43 + 4

Now we simplify to give:

3y = -39

So now we divide both sides by 3 to give our answer of:

y = -39/3
y = -13
We can substitute this into the original equation to check our answer:

-4 + 3(-13) = -43

-4 + -39 = -43
