For this case we have the following equation:

-6 =\frac{2}{9}x

From here, we must clear the value of x.

For this, we follow the following steps:

1) Place the 9 multiplying:

-6 (9) = 2x

-54 = 2x

2) Place the 2 dividing:

-\frac{54}{2} = x

-27 = x

3) Rewrite the result:

x = -27

Answer:

The result of the equation is:

x = -27

-6=\frac{2}{9}x\\ \\  -6*\frac{9}{2}=x \\ \\ -27=x

Hope this helps!

The coordinates of A, B, and C in the diagram are A (p, 4), B (6, 1 ), and C (9, q). Which equation correctly relates p and q? ↔
aivan3 [116]

Answer:

  D.  p + q = 7

Step-by-step explanation:

The slope of AB is ...

  mAB = (y2 -y1)/(x2 -x1) = (1 -4)/(6 -p) = -3/(6 -p)

The slope of BC is ...

  mBC = (q -1)/(9 -6) = (q -1)/3

We want the product of these slopes to be -1:

  mAB·mBC = -1 = (-3/(6 -p))·((q -1)/3)

  -(q-1)/(6 -p) = -1 . . . . cancel factors of 3

  q -1 = 6 -p . . . . . multiply by -(6 -p)

  q + p = 7 . . . . . matches choice D
