The best way I can explain the elimination method is, it's a method where you either add or subtract equations in order to get rid of a variable.
Answer:
its b
Step-by-step explanation:
its b i for some reason got it right
The point slope form of a line is written as y - y1 = m(x -x1)
Where m is the slope and x1 and y1 are the points on the line.
You are told the slope is 3 and the point is (2,-1/2)
x1 is 2 and y1 is -1/2
Replace those in the equation to get:
y- (-1/2) = 3(x-2)
Simplify to get the final answer:
y + 1/2 = 3(x-2)
I think you have to subtract 60% and 80% which you get 20%
Answer:
Step-by-step explanation:
90 by 20%
10%=9
20%=18
90-18=62
Hope u understand
