Multiplying fractions: multiply numerators and multiply denominators

1. 3/4 X -6/7 = -18/28 = -9/14

2. -2/7 X -3/7 = 6/49

3. 4 because 72/9 is 8.  -72/-9 is 8.  Two negatives makes a positive when multiplying and dividing.

Multiply (x-3)(4x+2)
Arisa [49]

Answer:

4x^2 - 10x - 6

Step-by-step explanation:

Use FOIL to distribute.

First

Outside

Inside

Last

F: x * 4x = 4x^2

O: x * 2 = 2x

I: -3 * 4x = -12x

L: -3 * 2 = -6

Now, put the answers together.

4x^2 + 2x - 12x - 6

Now, combine like terms.

2x and -12x are like terms.

2x - 12x = -10x

Our final answer is:

4x^2 - 10x - 6

Which ordered pairs could be points on a line parallel to the line that contains (3, 4) and (–2, 2)?
Olin [163]
The equation of the line containing the points (3, 4) and (-2, 2) is:
 y-yo = m (x-xo)
 Where,
 m = (y2-y1) / (x2-x1)&#10;&#10; m = (2-4) / (- 2-3)&#10;
 m = (-2)/(-5)&#10;&#10;m = 2/5
 (xo, yo) = (-2, 2)&#10;
 Substituting values:
 y-2 = (2/5) (x - (- 2))&#10;
 y-2 = (2/5) (x + 2)&#10;&#10; y = (2/5) x + 4/5 + 2&#10;&#10; y = (2/5) x + 14/5
 A parallel line is one that has the same slope:
 y = (2/5) x&#10; 
 An ordered pair that passes through this line is (0, 0).
 Answer:
 
A parallel line is:
 y = (2/5) x&#10;
 an ordered pair that goes through the parallel line is:
 
(0, 0)
