Jennifer's primary error was in line two, causing a chain reaction of errors in lines 3 to 5.

the correct solution is:

2x-8=40
2x=40+8

How do you explain a diameter of 0.00085 inches using scientific notation
dezoksy [38]

Answer:

8.5 E^{-4} inches

Step-by-step explanation:

        Scientific scientific notation  is where the super small / super large number is multiplied by a 10 (E) to the power of a number. Here, the number is smaller than 8.5 so our power must be negative. As we are making it four "places" bigger, we use the exponent of -4.

Hope this helps, have a nice day! :D

(06.01)The tables below show four sets of data:
Yakvenalex [24]
For it to be non-linear, the rate of change cannot be constant.  For the first table the rate is a constant 1 and the second table has a constant rate of -1.  The 3rd and 4th tables have no constant rate and thus are non-linear.

The 4th table is increasing while the 3rd table is decreasing.  

So the 3rd table, Set C, is the only non-linear negative association between x and y.
