Answer:
Not geometric
Step-by-step explanation:
In a geometric sequence, each term is multiplied by a common ratio to get the next term.
So if this is a geometric sequence, then dividing each term by the one before it should result in the same common ratio.
42 / 21 = 2
126 / 42 = 3
504 / 126 = 4
The ratios are different. This is not a geometric sequence.
Answer:
Electric TV, Airplane, Refrigerator, Computer, Steel
Step-by-step explanation:
4/52 = 2/27 After you divide that you get .074 after you round it to the three places.
The answer is 2.
3x+2y=3
2x-2y=7
solve both the equations
3x+2y=3
+2x-2y=7
5x=10
so we get
x=2
The line through that point and the origin has a slope of -1. It is perpendicular to the line you want, so the line you want has slope +1. Its equation can be written as
.. y = (x -4) -4
or, in standard form
.. x - y = 8
