21^2/0.219 = 2013.69863
2 significant figures are the 20, so the answer is 2000
Everything that is not in B.
8. 15. 13
Answer:
the answer is A
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
For Every x value the y value increases by 2
The slope (m) = -13.
We can use the slope formula:
m = (y2 - y1) / (x2 - x1)
Let (x1, y1) = (7, 26)
(x2, y2) = (12, -39)
Plug in the values into the formula:
m = (y2 - y1) / (x2 - x1)
m = (-39 - 26) / (12 - 7)
m = -65/5
m = -13
