How do I write a proof in geometry?

Answer:replication

Step-by-step explanation:

Final answer:

In the experiment, giving every student the same final exam is an example of direct control. This experimental design principle ensures that all other variables are kept constant so that any differences in the outcome can be attributed only to the variable being tested.

Explanation:

In this experiment studying the effect of the time of day a science class is taught on test scores, giving every student in the experiment the same final exam is an example of the experimental design principle known as direct control. The direct control principle ensures that all other variables except the one being tested (in this case, the time of day) are kept constant. This is done to make sure that any differences observed in the outcome (the test scores in this case) can be attributed only to the variable being tested. Therefore, all students taking the same exam ensures that the difficulty of the test doesn't affect the results.

To find the inverse, interchange the variables

so the Answer is 4 - 1 (x) = - 5 + 2x well thats your answer Hope this helps :)

Step 1:Replace f (x) with y

so y = x + 5 and the denominator 2

Step 2:Interchange the Variables x = y + 5 but the denominator stays the same

Now solve for y

since y is on the right of the equation switch sides so its on the left side

Step 3:y + 5 and the denominator 2 equals x

Step 4: Still solve for y Which is y = - 5 + 2x

Step 5: Solve for y and replace with 4 - 1 (x) to show the final Answer

Now the Answer is 4 - 1 (x) = - 5 + 2x

Lets see,

Hope this helps.
