The answer is D. -2x+5.
If we simplify the left side of the equation first given, we come to the expression -2x-10.
If we solve for D., we get the same results. Thus, because an equation with all the same variable terms and constants have infinite solutions, the answer is D.
Hope this helps!
Answer:
10,100,1000,-10,-100,-1000
Step-by-step explanation:
Answer:
1)
2)
We can find the individual probabilities and we got:
And the sum of the 3 values 0.6923+0.2307+0.0770= 1 so then we satisfy all the conditions and we can conclude that f(x) is a probability distribution.
Step-by-step explanation:
For this case we have the following density function:
In order to satisfty that this function is a probability mass function we need to check two conditions:
1)
2)
We can find the individual probabilities and we got:
And the sum of the 3 values 0.6923+0.2307+0.0770= 1 so then we satisfy all the conditions and we can conclude that f(x) is a probability distribution.
And if we want to find the following probabilities:
angle A = 30
(2x-9) = (2x+21)
+9 +9
2x=2x+30
-2x -2x
=30
Answer:
x = -52
Step-by-step explanation:
Let us solve for x.
Use cross multiplication to find the value of x.
Divide both sides by 3.
x = - 52
