Find slope
slope betwen 2 points (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
so
first make denoms same
denom is 10
(4/5,1/5) turns to (8/10,2/10)
(1/2,3/2) turns to (5/10,15/10)
slope=(15/10-2/10)/(5/10-8/10)=(13/10)/(-3/10)=13/-3=-13/3
use point slope
use (4/5,1/5)
y-y1=m(x-x1)
a point is (x1,y1) and slope is m
y-1/5=-13/3(x-4/5)
expand
wait, we don't need to do that, the only one with slope -13/3 is D
answer is D
Answer: 1.018
Step-by-step explanation:
The pH level of a substance indicates the concentration of hydrogen ions (
) in a solution and is calculated by:
In this case the hydrogen ion concentration is 
, where
. Hence:
This means this new substance is acid
Positive 3. Absolute values are never negative, they are either 0 or a positive. so -3 would be +3
Answer:
19
Step-by-step explanation:
in any parallelogram the diagonals bisect each other evenly. that means if JM = 19, ML is also 19. hope this helps
2 2/8=10/8 22/8=2 6/8 or 2 3/4
