Answer:
x=14
Step-by-step explanation:
9x = 3x + 84
9x-3x=84
6x=84
x=84/6
x=14
Each pound costs $1.19 .
So 15 pounds cost
(15) x ($1.19) = $17.85 .

Answer:
f(9) = -37
Step-by-step explanation:
f(n) = -5n + 8
f(9) = -5(9) + 8
f(9) = -45 + 8
f(9) = -37
Answer: OPTION C
Step-by-step explanation:
There are some transformations for a function f(x). Some of them are shown below:
1. If
, the function is shifted up "k" units.
2. If
, the function is shifted down "k" units.
3. If
, the function is shifted left "k" units.
4. If
, the function is shifted right "k" units.
In this case you know that the function "g" is the transformation of the function "f".
Observe that the function "f" intersects the y-axis at:

And the function "g" intersects the y-axis at:

Therefore, since both functions are 4 units apart, you can conclude that the function "f" was shifted down 4 units to get the function "g".
Then, the rule that shows that transformation is:
