Answer: C. The equations have the same solution because the second equation can be obtained by adding 6 to both sides of the first equation.
Step-by-step explanation:
You know that the first equation is:

And the second equation is:

According to the Addition property of equality:
If
; then 
Then, you can add 6 to both sides of the first equation to keep it balanced. Then, you get:


Therefore, you can observe that the second equation can be obtained by adding 6 to both sides of the first equation, therefore, the equations have the same solution.
If you want to verify this, you can solve for "x" from both equations:
- First equation:

- Second equation:

Answer:
6

đạo hàm cấp 2 của f(x) rồi thế 0 vào
SO we need 5 numbers that equal to 20, with 5 being the middle number, and ones being the most used number so
1 1 5 x y
According to this, x and y must equal 13 and both be bigger then 5. Because we can rule out every other number, x and y must be 6 and 7.
Your 5 numbers are 1, 1, 5, 6, 7.
You can make a proportion of 8/20 to 42/x and then simply cross multiply from there to solve for y
