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.

Step-by-step explanation:

x - 3y = 2

x=2+3y.....(1)

2x - 6y = 6

2(2+3y)-6y=6

it is not measurable.

What is the slope of the line that passes through the points (9, -1) and (4, -11)?
mixas84 [53]

Answer:

2

Step-by-step explanation:

We have two points so we can find the slope

m = ( y2-y1)/(x2-x1)

    = ( -11 - -1)/( 4 -9)

    = (-11+1)/( 4-9)

    -10/ -5

   = 2

Henry knows that the circumference of a circle is 18mc006-1.jpg inches. What is the area of the circle?
lesantik [10]
The complete question is:
Henry knows that the circumference of a circle is 18π inches. What is the area of the circle?

Solution:
Circumference (C) of the circle can be written as:

C=2 \pi r \\ \\ 18 \pi =2 \pi r \\ \\ r=9

Using this value of radius, we can find the Area(A) of the circle.

A= \pi  r^{2}  \\  \\ &#10;A= \pi (9)^{2}  \\  \\ &#10;A=81 \pi

Therefore, area of the circle having a circumference of 18π inches will be 81π inches²
