Answer:
n = -4
Step-by-step explanation:
- 5 (2n + 7) = 3n + 9 - 2n
- 10n - 35 = 3n + 9 - 2n
- 10n - 3n + 2n = 9 + 35
- 11n = 44
- n = 44/11
- n = 4
n = - 4
n=-4
its c! there isnt a decrease between x = -1 and x = 0, as when x = -1 y = 0 and when x = 0 y = 2, showing an increase of +2.
18
f(x) = 2(1/3)^x
[x = -2]
f(-2) = 2(1/3)⁻²
= 2(9)
= 18
