What do you mean, the answer is 12 and we know that because we combine the numbers
Steps to finding the inverse:
1. Replace f(x) with y.
2. Swap x and y.
3. Solve the equation for y.
f(x) = 2x - 10
1. y = 2x - 10
2. x = 2y - 10
3. Add 10 to both sides
x + 10 = 2y
Divide both sides by 2
(x + 10)/2 = y
y = (x + 10)/2
f^-1(x) = (x + 10)/2
I think 8. Plug in -4 for x. 1/2-4^2
Using pemdas -4^2 is 16 and 1/2•16 is 8. If there were parenthesis around 1/2x then 1/2•-4 would be -2 and -2^2 is 4 but since there aren’t parentheses then 8
Answer:
<h2>Non equivalent</h2>
Step-by-step explanation:
The equivalent between sets is determined by the number of elements. If two sets have the same number of elements, then they are equivalent sets.
In this case, a year has 12 months, and the US has 50 states. So, one month is not equal to 1 state because they have different natures and they represent a different proportion. A month represents 1/12 of a year and a state represents 1/50 of the total number of states.
Answer:
1/216
Step-by-step explanation:
Simplify the following:
6^(-3)
Hint: | In order to evaluate 6^3 express 6^3 as 6×6^2.
6^3 = 6×6^2:
1/(6×6^2)
Hint: | Evaluate 6^2.
6^2 = 36:
1/(6×36)
Hint: | Multiply 6 and 36 together.
6×36 = 216:
Answer: 1/216
