Answer:
1st question: y=1/3x-1
2nd question: y=-2/3x+9
Step-by-step explanation:
Y=mx+b form is what you are using
when a line in parallel to a line they have the same slop wich is m
when a line in perpendicular they have the opposite reciprocal
Examples: 2/5 opposite reciprocal would be -5/2
The decimals are the same and are equal to each other. It is just that one decimal has a 0 after the 6 and the other one does not. You can write it either way. So both would be equal and both would be correct!
Hope this helps!
Can u plz mark me as brainliest? I really need it!
Lets say we represent the amount of time she could ski.
So it would be x = the amount of time she skis
And 5x would represent how long it took her to climb
and she took 9 minutes to climb.
So what we would do first is put it in a equation like this
x + 5x = 9
Now we have 6x = 9
Divide 9 by 6x, and we get x = 15
So multiply 1.5 by 5 and the answer would be 7.5
Hopefully this helped. :)
