Step-by-step explanation:
Solution,
No. of people who participated= 20
No. of people who didn't participated= 15
Total number of people= 20+15= 35
Now,
Percentage of people who didn't participated
=No. of people who didn't participated/Total number of people×100%
=15/35×100%
=42.86%
Again,
Percentage of people who participated
participated=No. of people who participated/Total number of people×100%
=20/35×100%
=57.14%
A. m = 0 || This is incorrect, because m being equal to 0 is a solution in and of itself.
B. m = m || This is incorrect, because m being equal to itself means that there are an infinite number of solutions.
C. 2m + 1 = m - 2 | m = -3 || This is incorrect, because m can be solved for and has a solution.
D. m + 4 = m - 4 | 4 = -4 || This is correct because 4 is not equal to -4, and thus there is no solution.
Hope this helps!! :)
Answer:
20%
Step-by-step explanation:
100mL is the same has 100 grams. Therefore 20 grams of a 100 gram solution would be 20% of the solution.
Answer:
y = x+6
Step-by-step explanation:
You can find an equation by using the 2-point form of the equation for a line:
y = (y2 -y1)/(x2 -x1)·(x -x1) +y1
Filling in the given values, we have ...
y = (9 -5)/(3 -(-1))·(x -(-1)) +5
y = (4/4)(x +1) +5 . . . . simplifying a bit
y = x +6
Answer:
y=2x+4
Step-by-step explanation:
the y-intercept is the y value of the point given. in the slope form, 2 would be your m
