Answer:
1) intersection of both lines is the solution: (-3, 1)
2) y = -1/6x + 1 will produce a perpendicular line and intersect at only one point (slopes of 6 and -1/6 are opposite and reciprocal, thereby producing perpendicular lines)
3) 'b' can be any value except 1
Step-by-step explanation:
25%
Her profit is $20,000 on her cost of $80,000, so is ...
20,000/80,000 × 100% = 25%
146.6
0.47 * 312=146.64 when rounded to the nearest tenth that = 146.6
