Answer:
n = 9
Step-by-step explanation:
Step 1: Write equation
-4(9n + 9) = -12(4n - 6)
Step 2: Solve for <em>n</em>
<u>Distribute:</u> -36n - 36 = -48n + 72
<u>Add 48n to both sides:</u> 12n - 36 = 72
<u>Add 36 to both sides:</u> 12n = 108
<u>Divide both sides by 12:</u> n = 9
Step 3: Check
<em>Plug in n to verify if it's a solution.</em>
-4(9(9) + 9) = -12(4(9) - 6)
-4(81 + 9) = -12(36 - 6)
-4(90) = -12(30)
-360 = -360
The original statement is true!
the converse: If 2 lines do not intersect, they are parallel
the converse is false, the lines could be skew.

Answer:
A. 4x + 2y = 8
Step-by-step explanation:
The slope is -2/1 and the y-intercept is at (0,4). If you start at (0,4), go <u>down</u><u> </u><u>2</u><u> </u><u>units</u><u> </u><u>and</u><u> </u><u>1</u><u> </u><u>unit</u><u> </u><u>right</u>.
