Answer:
x = -9
Step-by-step explanation:
x = -9 would be the slope because when you see the two points for each coordinate there is no x value but we do see a straight line and we see that there is no y-intercept. So, x= -9 would be the answer. Hope this helps.
Given that and , we can say the following:
Now, remember what happens if we have a negative square root: it becomes an imaginary number. We don't want this, so we want to make sure whatever is under a square root is greater than 0 (given we are talking about real numbers only).
Thus, let's set what is under both square roots to be greater than 0:
Since both of the square roots are in the same function, we want to take the union of the domains of the individual square roots to find the domain of the overall function.
Now, let's look back at the function entirely, which is:
Since is on the bottom of the fraction, we must say that , since the denominator can't equal 0. Thus, we must exclude from the domain.
Thus, our answer is Choice C, or .
<em>If you are wondering why the choices begin with the symbol, it is because this is a way of representing that lies within a particular set.</em>
X is less than or equal to 3
X is less than 9
X is less than -5
X is greater than or equal to 13
Answer:
5√3 / 2
Step-by-step explanation:
tan 30 = ( 5 / 2 ) / y
1 / √3 = 5 / 2y
2y = 5√3
y = 5√3 / 2
Answer: -2/3
