2(x + 2) = x - 4
2x + 4 = x - 4
2x - x = -4 - 4
x = -8
Solution: x = -8
Answer:
All real numbers
Step-by-step explanation:
There is 3 possible solutions to a linear equation:
- One solution -a unique x value that makes the equation true
- No solution - a false statement is given after solving without a value for x
- Infinite solution - a true statement is given after solving without a value for x
Solve using inverse operations:
4(a+2)=14-2(3-2a)
4a+8=14-6+4a
4a-4a+8=8+4a-4a
8=8
Is 8=8? Yes. Therefore this is a true statement with no value for x. Infinite solutions or all real numbers.
Answer:
3/8 is less than 11/12
Step-by-step explanation:
3/8 is 0.375 as a decimal
11/12 is 0.92 as a decimal
so 3/8 is less than 11/12
It always helps to turn them into decimals...
Answer:
Please find attached the required inverse of a function chart
Step-by-step explanation:
The inverse of a function is found by reversing the operations of the function
The inverse of the function f(x) = 2·x - 4 is found as follows;
x = 2·x - 4
x + 4 = 2·x
x = (x + 4)/2 = x/2 + 2
Therefore, the inverse of the function f(x) = 2·x - 4 is f(x) = x/2 + 2
The inverse function is plotted by generating data points as follows;
