Answer 5

B and C are correct, but I'm not too sure A is at first glance... Let me work it out :)

Answer 6

ok :)

Answer 7

A is incorrect: it is not 25.28 hours. :) Think about it logically, for everyone one hour watching TV (x) you lose ____ hours studying (y). I'll give you a hint: it has to do with your slope...

Answer 8

-0.76

Answer 9

Excellent! Just remember to write 0.76, not -0.76 because the negative is understood.

Explanation: The slope we know is -0.76/1 and we know that it is also the rise/run. X is the run, and we are given that it is, in this problem, 1 hour. Therefore, y must be -0.76 because it is the rise!

Does that make sense?

Answer 10

yep @asett is right and well for B and C please give exact answers not rounded approximations as your questions says so change B to 26 and C to 12 and A is 0.76 because it is decreasing at a rate negative sign is omitted :)

Answer 11

But it is asking for exact answers, which are 26.04 and 12.36 respectively, not rounded approximations, which is 26 and 12. Just like you wouldn't say 1 for the answer 0.76.
