Step one:
ALWAYS set equation equal to zero, which in this case has already been done for us.
Step two:
Figure out what formula you need to use in order to solve in this case I'd use the Quadratic formula.
a=1
b=9
c=2
Quadratic formula:

Then you would plug in the information.

The solve for what is underneath the square root ONLY.

Since you cannot solve this any further, your final two answers are...

I would tell her not to because not only does she have to pay back the 1000 but now she also has to pay back the interest on it. She should just wait or save up until she has 1000 that way she dont gotta pay extra.

Since 25% is 1/4, you multiply 60 by 1/4 to get how many students took Spanish class last year. So, 60 times 1/4 is 60/4, which is 15. Then you subtract 15 from 60 to get 45. So, 45 students took Spanish class last year.
Answer:
1-nonlinear it is not consistant
2- a increasing, b constant, c decreasing
3- 'a' walking away from hole, 'b' rests, 'c' goes back to hole (b could also be gather, as in food)
4- 8cm per second
work 16cm/2sec=8cm/1sec
Step-by-step explanation:
