6 - 3(2x - 4) = 2(1 + x)
6 - 3(2x) + 3(4) = 2(1) + 2(x)
 6 - 6x + 12 = 2 + 2x
 6 + 12 - 6x = 2 + 2x
 18 - 6x = 2 + 2x
 + 6x + 6x
 18 = 2 + 8x
 - 2 - 2 
 16 = 8x
 8 8

Find the slope of a line parallel to a line that contains the points (8, -3) and (2, 5).

Illusion [34]

Answer:

$-\frac{4}{3}$ (Your answer choices were really confusing, so I just put the plain answer)

Step-by-step explanation:

To find the slope of a line with just two points, we can use the formula $\frac{y2-y1}{x2-x1}$ . In this case, $\frac{5-(-3)}{2-8}$ . This is $\frac{8}{-6}$ . This reduces to $-\frac{4}{3}$

Find two consecutive odd integers such that seven times the first equals five times the second.

fredd [130]

Answer:

Odd integers are always one more that an even integer:

1st: 2n+1

2nd: 2n+3

Step-by-step explanation:

14n+7 = 10n+15

4n = 8

n = 2

------------

1st: 2n+1 = 5

2nd: 2n+3 = 7

7x=5*(x+2)

7x=5x+10

7x-5x=10

2x=10

x=5
