Find the constant of variation k for the direct variation 2x +6y = 0

1 answer:

5 0

A relationship between two variables in which one is a constant multiple of the other. The constant here is also called the constant of variation. In order to obtain this value, we manipulate the equation by isolating the variables. We do as follows:

2x +6y = 0
y = -x/3

Therefore, the constant of variation is -1/3. Hope this answers the question. Have a nice day.

Find the 8th term of the arithmetic sequence -2x+5−2x+5, -7x+8−7x+8, -12x+11, ...

miss Akunina [59]

Answer:

-37x+26

Step-by-step explanation:

The x-coefficients have the sequence ...

-2, -7, -12, ...

which has first term -2 and common difference of (-7 -(-2)) = -5. Then the 8th x-coefficient is ...

-2 + (-5)(8 -1) = -37

The constants have the sequence ...

5, 8, 11, ...

which has first term 5 and common difference 8 -5 = 3. Then the 8th constant term is ...

5 +(3)(8 -1) = 26

The 8th term of the sequence is -37x +26.
