Y = 3x - 7...slope here is 3 and y int is -7
3x + 9y = 9
9y = -3x + 9
y = -1/3x + 1....slope here is -1/3 and y int is 1
the slopes 3 and -1/3 are negative reciprocals of each other...therefore, ur lines are perpendicular
12s, you don’t have a value for s, so the problem can’t be fully solved but if you did you would multiply 12 by her speed
Hope this helps
Answer:
15/x=1/3
Step-by-step explanation:
The quotient of 15 and a number=15/x=1/3
15/x=1/3
It is decreased by a factor of 3. You can determine this by realizing that one inch original equals 3.3 feet, but the equals 1.1 feet, and 3.3/1.1 = 3.
