Answer:
The 2 equations are E = 2K and K = E-3
Step-by-step explanation:
Let the height of Eric be E
Let the height of Kevin be K
Eric is twice as tall as his little brother Kevin
E = 2K
Kevin is also three feet shorter than Eric
K = E-3
The 2 equations are E = 2K and K = E-3
Answer:
C
Step-by-step explanation:
It depends really. If you stay close to the present, then predicting future results isn't too bad. The further you go out, the more unpredictable things get. This is because the points may deviate from the line of best fit (aka regression line) as time wears on. Of course, it also depends on what kind of data we're working with. Some pairs of variables are naturally going to correlate very strongly together. An example would be temperature versus ice cream sales.
The last one. In arithmetic sequence, the difference between the terms is constant, in this case, the difference is 3
