Answer:
m=-3
Step-by-step explanation:
m2-9=0
2 divied by 9 =3
when you have a positive number and a negitive number =a negitive
I think you get the point
The function would be h = 270 - 2.5s, where h is the height (in feet) and s it the time (in seconds) that has passed.
The 270 represents the initial value, which is given. We are told that the initial height of the block is 270 feet.
2.5s represents the feet that it has descended. We know the block is lowered at a rate of 2.5 feet per second. Multiplying this by s, the time, will give us how much it has descended.
Answer:
in one minute they rake
leaves working together.
Step-by-step explanation:
If Maya rakes the leaves in x minutes, then, in one minute she rakes
leaves.
In the case of Carla, if she rakes the leaves in y minutes, in one minute she rakes
leaves.
Therefore, to know the portion of leaves they can rake in one minute working together, we need to sum up both of the portions each one of them rake in one minute, this gives us: 
Now, to simplify this expression:

Thus, in one minute they rake
leaves.
