Answer:
If the x-6 is all under the sqrt, the last answer is right:
6<= x <= infinity
If only x is under the sqrt and - 6 is NOT under the sqrt, then:
0 <= x <= infinity is the correct answer.
Step-by-step explanation:
You can look at the equation and or graph to determine the domain of a function. The domain is all the x's that may go into the equation or all the x's on the graph of the function. Inside of a squareroot symbol the number inside there must be positive. While considering the equation, only x's that keep that inside positive can be used.
For sqrt(x-6), x has to be 6 or bigger.
For sqrt(x) - 6, x has to be 0 or bigger.
You'll need to provide a bit more information for me to answer this. I.e are you trying to find out how much money will be made after a certain number of years? e.c.t
Answer:
50
Step-by-step explanation:
Assuming you're solving for Q, the first step is to multiply the first set of parenthesis by 0.10:
0.10(72-Q) = 7.2 - 0.1Q
The next step is to combine the terms that have Q in them:
7.2 - 0.1Q + 0.25Q = 14.7
7.2 + 0.15Q = 14.7
Now isolate 0.15Q:
0.15Q = 14.7 - 7.2
0.15Q = 7.5
Divide 7.5 by 0.15 to solve for Q:
Q = 7.5/0.15 = 50
