Answer:
3
Step-by-step explanation:
2(x + 1) = 3(5 - x) + 2
Distribute,
2(x + 1) = 3(5 - x) + 2
2x + 2 = 3(5 - x) + 2
Rearrange terms,
2x + 2 = 3(5 - x) + 2
2x + 2 = 3(-x + 5) + 2
Distribute,
2x + 2 = 3(-x + 5) + 2
2x + 2 = -3x + 15 + 2
Add the numbers,
2x + 2 = -3x + 15 + 2
2x + 2 = -3x + 17
Subtract 2 from both sides,
2x + 2 = -3x + 17
2x + 2 - 2 = -3x + 17 - 2
2x = -3x + 17 - 2
2x = -3x + 15
Add 3x to both sides,
2x = -3x + 15
2x + 3x = -3x + 3x + 15
5x = -3x + 3x + 15
5x = 15
Divide both sides by the same factor (15),
5x = 15
5x/5 = 15/5
x = 15/5
x = 3
Hence, the answer is 3.
Well first of all, let's define what an integer is...
Integers are numbers such as -2, -1, 0, 1, 2 etc etc.

If f(5)=12,
f(6)=0.3*f(6-1)
= 0.3*f(5)
= 0.3*12
= 3/10 * 12
= 36/10
= 3.6
We now know that f(6)=3.6
Now:
f(7)=0.3*f(7-1)
= 0.3*f(6)
= 0.3*3.6
= (3/10) * (36/10)
= 108/100
= 1.08
Answer:
f(7)=1.08
