Yes, it is an integer because it is a whole number.
Hi there
0.06x+0.10 (30000-x)=2560
Solve for x
0.06x+3000-0.1x=2560
0.06x-0.1x=2560-3000
-0.04x=−440
X=440/0.04
X=11000 invested at 6%
30000-11000=19,000 invested at 10%
Hope it helps
ANSWER
B. 1
EXPLANATION
The given function is

This is a piece-wise defined function.
We want to find f(1)
We substitute x=1 into f(x)=x because, 1 belongs to the interval,
1≤x≤5
f(1)=1
The correct answer is B.
Answer:
w = -7z/2
Step-by-step explanation:
Our goal is to isolate w
1. subtract 3w from both sides to get 2w+9z = 2z
2. Subtract 9z from both sides to get 2w = -7z
3. Divide both sides by 2 to get w = -7z/2
We cannot simplify further, so this is our answer.
For a number to be divisible by 6, it must also be divisible by 2 and 3. Therefore, we need to check if a number is even and then check if the sum of the digits is divisible by 3.
