Answer: B
Step-by-step explanation: to find the mean you add all of the values and divide it by the number of values you added. so it would be (13+14+14+14+14+14+15+15+15+15+15+15+16+16+17)/15 which equals 14.8
Answer:
Step-by-step explanation:
<u>Given lines:</u>
- - 6x + 3y = -9 and
- y + 1 = -3(x + 2)
To determine the answer we need to compare slopes of the lines.
Parallel lines have same slopes, perpendicular lines have negative-reciprocal slopes.
<u>Let's put them in slope-intercept form:</u>
- - 6x + 3y = -9 ⇒ -2x + y = - 3 ⇒ y = 2x - 3
- y + 1 = -3(x + 2) ⇒ y + 1 = -3x - 6 ⇒ y = -3x - 7
As we see the slopes are 2 and -3, so the lines are neither parallel nor perpendicular
