Step-by-step explanation:
Sometimes the best thing you can do with this kind of question is just to graph it. The graph is below. Done on Desmos. It shows that the min is at (8,9)
So the answer is B.
Answer:
x=2, y= 4
Step-by-step explanation:
Equation 1 is 2x-4y = -12
Equation 2 is 2x+y = 8
Subtracting the two equations gives -4y-y = -12-8 (The 2x and the other 2x cancel each other out).
Simplifying we get -5y = -20 and y =4
Substituting y =4 into original equation back we get 2x -4(4) =-12
This equals 2x -16 =-12 and 2x = 4 and x =2
Answer:
The answer is B
Step-by-step explanation:
I just took the quiz on Edge
Given :
Positive integers 3, 4, 5, 6, 6, 7, and x are all equal.
To Find :
The mean, median, and unique mode are all equal , find x.
Solution :
Median is the middle number in sorted list.
So, median = 6
Also, mode is the number with highest frequency.
mode = 6
So,
mean = mode = median
Hence, this is the required solution.
Anything that with a denominator that is a multiple of 4, for example:
,
,
,
, and so on.
Hope this helps you =)
