Answer:
3x - 7
Step-by-step explanation:
This questions asks about the subtraction of functions. To find the answer, we can subtract the same way we would subtract polynomials.
Subtracting Expressions
First, set up the subtraction problem by taking the expression for f(x) and subtracting the expression equal to g(x) from it.
This looks like:
Next, distribute the negative to the second binomial
Then, combine like terms
Since we are not given a x-value, this is the final answer.
Solving for an X-Value
If you are given an x-value, the best way to solve the equation is to first solve each function and then subtract.
For example, using the same rules for each function let's solve (f-g)(2).
First, solve for f(2) and g(2)
Then, subtract the 2 values
Answer: C. 39 degrees
Step-by-step explanation: Hope this help :D
perimeter = 2L +2W
from the problem we know P = 74 and W=L-9
so 74 = 2L +2W
74 = 2L+2(L-9)
74 = 2L + 2L -18
74 = 4L-18'
92 = 4L
L=23
W=14
We need to convert 2 kilograms into pounds. First, we find how many pounds are in 1 kilogram.
There are about 2 pounds in one kilogram.
Then we multiply 2 pounds by 2 kilograms to convert the 2 kilograms into pounds.
2 * 2 = 4
So, the answer to this question is 4 pounds.
