Answer:
30
Step-by-step explanation:
Since you know all the angles have to add up to 180 degrees, you add 102 and 48. That is 150. 180 degrees-150 degrees equals 30 degrees.
Answer: -60
Step-by-step explanation:
5 - 1/3x = -15
-1/3x = -20
(-3/1)-1/3x=-20(-3/1)
x = -60
Answer: D.The domain and range of the function are the same.
Step-by-step explanation: Given function f(x)=-√-x.
The given function is a square root function and we have minus sign in front of x inside square root.
A square root always defined for positive values or 0.
In order to get a positive number or 0 inside square root, let us solve the inequality:

On dividing both sides by -1, the inequality sign would get flip and we get
<h3>Domain:

</h3>
We can see that we have a negative sign in front of square root. So, the value of f(x) would be always a negative number or 0.
<h3>Therefore, range would also be :

.</h3><h3>Therefore, correct option is D option.</h3>
Answer:
X= -3
Step-by-step explanation:
(4+5)-1/3(40-4)=X
X=9- 1/3(36)
X=9-12
