F(x) = 2x + 1
To find the inverse of a function you just need to switch the x by y or vice-versa:
-> y = 2x + 1
-> x = 2y + 1
After that you isolate the y again:
-> 2y = x - 1
-> y = (x-1)/2
-> f^-1 (x) = (x-1)/2
Answer:
What's the problem? There's no example...
98cm^2 - bigger triangles are 28 each, bottom one is 14. (28 x 3) + 14=98
Answer:
The solution to the inequality is:

The solution graph is also attached below.
Step-by-step explanation:
Given
We are given the expression

To determine
Solve for x
Given the expression

Subtract 5 from both sides

Simplify

Multiply both sides by 3

Simplify

Thus, we conclude that:

Therefore, the solution to the inequality is:

The solution graph is also attached below.
Answer:
4/21
Step-by-step explanation:
Multiply 1 and 4. Then multiply 3 and 7. So 1x4=4, and 3x7=21. Therefore, the answer is 4/21. In multiplying fractions, you just multiply straight across (: (Hope this helps)
