This is linear. 8x-5y=15
-5y=15-8x
Divide -5
Y=8/5x-3.
Start at -3 on y axis and go down 8 points and right 3.

Select the correct answer.
Scientists studying biodiversity of amphibians in a rain forest have discovered that the number of species is decreasing by 2% per year. There are currently 74 species of amphibians in the rain forest. Which logarithmic function models the time, , in years, it will take the number of species to decrease to a value of n?
The answer is D.
Step-by-step explanation:
Answer:
x^2 - 6x - 4 = x^2 - 6x + 9 - 13 = x^2 - 2.x.3 + 3^2 - 13
= (x-3)^2 - 13
(m = -3 and n = -13)
Answer:
Aubrey ran 3 1/3 miles further than what she walked.
Step-by-step explanation:
This would be your basic subtraction problem. So, 13 1/6 - 9 5/6.
Since you can't subtract 5/6 from 1/6, let's borrow from 13. Now, instead of 13, it would be 12. Adding the whole (1) or 6/6 to the 1/6, you'll get 7/6. Now you can subtract. 7/6 - 5/6 = 2/6. Moving on, 12 - 9 = 3.
Therefore, your answer is 3 2/6. In simplified terms, it would be 3 1/3.
Answer: 4 and 6
Step-by-step explanation:
Because 14/17 is greater than half, you round up to the 4, same goes for the 11/15, it's greater than 1/2 (0.5) so you would round up to the 6.
