Answer:
The answer is d
Step-by-step explanation:
Start with the y intercept and them go up two places over 1
Error: They subtracted 9x from both sides when they should have subtracted 12. You can’t subtract unlike terms
Correct: x=-5/16
Subtract 12 from both sides to get -5 on the left and add 7x and 9x to get 16x. Divide both sides by 16 to isolate x.
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.
the answer is B. A = 2.449489743, B = 1.414213562, c = 3.141592654, and D = 2.886751346. so B is the lowest.
