Given lines:
- 3x + y = 1 and y + 6 = - 3x
Convert both equations to slope-intercept form of y = mx + b:
- 3x + y = 1 ⇒ y = - 3x + 1
- y + 6 = - 3x ⇒ y = - 3x - 6
Slopes are same, so these are parallel lines, and the distance between parallel lines is:
, where b₁, b₂ - y-intercepts, m- slope
Substitute and calculate:
Answer:
16.67% of cases of tapes were sold.
Step-by-step explanation:
We are given the following in the question:
Number of cases of tapes sold = 24
Thus is 20% of tapes left.
Let x be the total number of tapes left.
Thus, we can write:
Thus, total number of tapes =
Percentage of tapes sold =
Thus, 16.67% of cases of tapes were sold.
