Answer:
Parallel
Step-by-step explanation:
Parallel lines have the same slope but different y-intercepts. If you multiply the top equation by 2, you get:
2(12x + 4y = 16)
24x + 8y = 32
This shows that both lines have the same slope, but then you find the y-intercepts, they are different:
1st equation y-int = 4
2nd equation y-int = 9/2 or 4.5
Answer: it will take 6 months for both gyms to cost the same.
Step-by-step explanation:
Let m represent the number of months that it will take for the cost of both gyms be the same.
At one gym, there is a $12 start-up fee, and after that each month, m, at the gym costs $20. This means that the total cost for m months is
12 + 20m
At another gym, each month at the gym costs $22. This means that the total cost for m months is 22m
For both costs to be the same, the number of months would be
12 + 20m = 22m
22m - 20m = 12
2m = 12
m = 12/2 = 6
Answer:
4
Step-by-step explanation:
first you simplify, so -1-3=-4.
|-4|
the absolute value of negative four is just four with all signs removed (in this case, negative sign)
4
Answer:
162km
Step-by-step explanation:
dis=30km
time=5/12hr
speed =(dis÷time)
30÷5/12
30×12/5=72km/h
sp=72km/h
time=21/4hr
dis= sp×time
72×9/4=162km
