Factor the expression 54x+81 using GCF

1 answer:

4 0

To factor 54x+81 using the greatest common factor, find the GCF of 54 and 81 by listing all factors and finding the biggest.

54 - 1, 2, 3, 6, 9, 18, 27, 54
81 - 1, 3, 9, 17, 81

9 is the gcf, so factor it out.

54x+81 = 9(6x + 9)

A line contains the points R (-1, 8) S (1, 4) and T (6, y). Solve for y. Be sure to show and explain all work.

Nikitich [7]

Given:

A line contains the points R(-1, 8), S(1, 4) and T(6, y).

To find:

The value of y.

Solution:

Three points are collinear if:

$x_1(y_2-y_3)+x_2(y_3-y_2)+x_3(y_1-y_2)=0$

A line contains the points R(-1, 8), S(1, 4) and T(6, y). It means, these points are collinear.

$-1(4-y)+1(y-8)+6(8-4)=0$

$-4+y+y-8+48-24=0$

$2y+12=0$

Subtract 12 from both sides.

$2y=-12$

Divide both sides by 2.

$y=\dfrac{-12}{2}$

$y=-6$

Therefore, the value of y is -6.
