<span>A) 3x + 3y + 2z = -5
B) x + y + 3z = -4
C) 2x + 2y + 5z = -7
I don't think this system of equations has a solution.

Answer:
still dk
Step-by-step explanation:
The first term in our arithmetic sequence = 13
The common difference of our arithmetic sequence = 17 - 13 = 4
The formula for finding an equation for any arithmetic sequence is a(n) = A + B(n - 1)
A = the first term
B = the common difference.
Let's plug our numbers in.
a(n) = 13 + 4(n - 1)
Let's check to make sure we're correct.
a(1) = 13 + 4(1 - 1) = 13 + 4(0) = 13 + 0 = 13
a(2) = 13 + 4(2 - 1) = 13 + 4(1) = 13 + 4 = 17
That verifies that our formula is correct.
In conclusion,
a(n) = 13 + 4(n - 1)
It is asking for the volume of the cube
Well...you haven't given any values,but:
When a point is reflected over the y-axis, the signs of the x-coordinates are reversed while the signs of the y-coordinates remain the same.
Example:
Let's say point A is (3,5). When you reflect it over the y-axis, it becomes (-3,5).
Hope this helps!
