<span>This question, in my opinion, is not well stated. If f(x) = √x, as the question statement seems to say, then the domain is not x<7. Rather, the domain is x≥0.
If f(x) is not the square root function, but say f(x) = √(7-x) then the domain is x≤7, and for this function then the appropriate answer is d), since the x-term inside the radical has a negative coefficient.</span>
The <em>correct answer</em> is:
Causation.
Explanation:
As the battery charge of a phone decreases, the amount of time you can perform any action with the phone decreases, including the number of minutes you can talk. This is because after a certain amount of time, there will be no more battery charge, which means you will not be able to use the phone at all.
Answer:
Step-by-step explanation:
X = 26 ; y = 27
(x − y)2 = x² − 2xy + y²
(26 - 27)² = 26² - 2(26)(27) + 27²
(-1)² = 676 - 1404 + 729
1 = 1405 - 1404
1 = 1
<h3>
Answer: D) 4</h3>
Explanation:
Start at the point (-1,-4). In order to move to (0,0), we must do the following two steps:
- Move 4 units up
- Move 1 unit to the right
This indicates slope = rise/run = 4/1 = 4.
You could use the slope formula to get this same result.
