Answer:
it's hard to tell the exact question being asked...
y = 
or
y = 
if y =
then Domain is [0 ,∞ )
if y =
then Domain is [-1 ,∞ )
Step-by-step explanation:
Answer:
A is the correct one
Step-by-step explanation:
Answer: The slope is 0.5 Or 1/2
Step-by-step explanation:
Domains of functions are the values that <em>can</em> be plugged into the function and not "break" it. By "break" I mean that the denominator cannot be 0, in this case. If the denominator is 0, we will get a divide by 0 error, and thus, we must restrict the domain. All values of x will work except 9/4:

Let's plug in 9/4 and see what happens:

So, plugging in 9/4 results in denominator equalling 0. Therefore, we must restrict the domain so that x ≠ 9/4. Your answer is All real values of x such that x ≠ 9/4.
Answer:
A) 24
B) 12
C) 54
Step-by-step explanation:
a+33=57
a=57-33
a=25
