Use the pythagorean theorem (a squared plus b squared equals c squared). 10 squared is 100 and 4 squared is 16. x squared must equal 116. x must therefore equal around 10.7703296143
You add all the values together based on the dot plot.
1 dot on 16
4 dots on 17
4 dots on 19 ....etc.
16 + 17(4) + 19(4) + 21 + 22(2) + 23 + 25 = 273
Answer:
y=2x-3 is in Slope-Intercept Form
Answer:
There could be several answers.
You could add 27,000 each time (72,000)
or you could find what percentage 18,000 is of 45,000, then use that percentage of increase to figure out the next number for 45,000 (72,000)
Surprisingly, you will end up with 72,000 in both of these configurations.
