Christopher needs to create so that his time spent will be the same as his current time, the equation could be: 2.4x = 1.2x + 15
Answer:
what is the question. please provide a question.
I think x is equal to 14.7
Answer: The correct option is (D) 
Step-by-step explanation: We are given to find the domain of the following function:

The domain of a function y = f(x) is the set of all possible x-values which will make the function defined or will output real y-values.
That is, for the function (i), the domain will be given by all those values of x for which
is real.
Now, the values of y will be real only if the expression under square root is greater than or equal to 0.
Therefore, the domain of function (i) is

Thus, the domain of the given function is 
Option (D) is CORRECT.
<span>Selections (a, b, d) are the most correct answers. To begin, 2x is equal to -8 when x is (-4). Adding 0 to this (for y) gives -8, which is the answer for the first equation. Doing the same for the second equation gives (-4 - 0) = -4, which shows that the second equation is also correct. Since both equations are satisfied by this ordered pair, it shows that the pair (-4,0) is a solution to the entire system.</span>
