Answer:
Step-by-step explanation:
A. 4.2E6 because when putting a number into scientific notation, you would want one number in front of the decimal place and then the trailing numbers would follow. The exponent or E stand for how many numbers are after the decimal, which in this case would be 6.
4,200,000 → 4.2 x 10^6 which is equal to saying 4.2E6
Tip: If the exponent is negative than the decimal would go in the opposite direction. For example:
4,200,000 → 4.2 x 10^-6 would not equal each other because 4.2 x 10^-6 means 0.000004, six numbers would be behind the decimal.

By graphing x = -1, you will see that the line splits this rhombus in two equal halves
Answer:

Step-by-step explanation:

value of home in 1991= 105% of 170000
value of home in 1992= 105%×105% of 170000
value of home in 1993= 105%×105%×105% of 170000
=$196,796.25
