6x - y = 31 so y = 6x - 31
substitute y = 6x - 31 into 3x + 7y = 8
3x + 7y = 8
3x + 7(6x - 31) = 8
3x + 42x -217 = 8
45x = 225
x = 5
y = 6x - 31
y = 6(5) - 31
y = 30 - 31
y = -1
answer
x = 5 and y = -1
Answer:
The statement that could be false is;
(C) The function has a relative minimum at x = 6
Step-by-step explanation:
The given parameters are;
The function is continuous in the interval 0 ≤ x ≤ 9
The function is not differentiable at x = 6
f prime (x) = Negative for 4 < x < 6, and positive for 6 < x < 8
Therefore, at x = 6, the function is vertical
The statement that could be false is that the function has a relative minimum at x = 6.
Answer:
A
Step-by-step explanation:
Hi! The sum means to add
(3+4=7)
The quotient mean to divide
(1 divided by2 = .5)
So 7 divided by .5
=14
Really hope this helped!
Answer:
1.8
Step-by-step explanation:
1st step
To find the mean absolute deviation of the data, start by finding the mean of the data set.
2nd step
Find the sum of the data values, and divide the sum by the number of data values.
3rd step
Find the absolute value of the difference between each data value and the mean: |data value – mean|.
4th step
Find the sum of the absolute values of the differences.
5th step
Divide the sum of the absolute values of the differences by the number of data values.
