Answer:

3

Step-by-step explanation:

A direct variation is of the form

y = kx

We know x and y so we can find k

81 = k *27

Divide each side by 27

81/27 = 27k/27

3=k

The constant of variation is 3

Solve the following system using the SUBSTITUTION method.<br> x - 3y = 2<br> 2x - 6y = 6
notka56 [123]

ANSWER:

  • x – 3y = 2 ...(1)
  • 2x – 6y = 6 ...(2)

On solving eq(1), we get

  • x – 2 = 3y
  • x – 2/3 = y

Plug the value of x in eq(2)

  • 2x – 6(x - 2/3) = 6
  • 2x – 2(x – 2) = 6
  • 2x – 2x + 4 = 6
  • 0 = 6 – 4
  • 0 ≠ 2

So, given system of equations is not correct.

I think it is option A. Order matters; if the order is interchanged, the position of the figure will most likely change. You can try it out yourself too! Hope I helped! Happy Holidays!

5x – 2x + 7 – x = ?x + ?
fomenos

Step-by-step explanation:

5x – 2x + 7 – x = ?x + ?

I need the answer for "no solution" and "infinite solutions".

NO SOLUTION:

no solution because any value you give to x is not solvable, it remains +7

5x – 2x + 7 – x = ?x + ?

2x = 2x + 7

INFINITE SOLUTION

infinite solutions because any value you give to x is solvable

5x – 2x + 7 – x = ?x + ?

5x – 2x + 7 – x = 2x + 7

2x + 7 = 2x + 7
