Answer:
x = 8
Step-by-step explanation:
In equilateral, the length of the sides are equal.
12x - 22 = 10x - 6
Add 22 to both the sides
12x = 10x - 6 + 22
12x = 10x + 16
Subtract '10x' from both sides,
12x -10x = 16
2x = 16
Divide both sides by 2
x = 16/2
x = 8
Answer:
C
Step-by-step explanation:
Let's consider the first answer choice:
The times in the semifinals were faster on average than the times in the finals.
We don't have to calculate the mean values of each distribution because we can see visually that the center of the final round distribution is lower than the center of the semifinal round distribution.
Since lower times are faster, we can't say that the times in the semifinals were faster on average than the times in the finals.
Hint #22 / 3
Now, let's consider the second answer choice:
The times in the finals vary noticeably less than the times in the semifinals.
We can see visually that the final round distribution is more spread out than the semifinal round distribution. We could calculate MAD or IQR from these displays, but we can see that the range of the final round distribution is larger.
So we can't conclude that the times in the finals vary noticeably less than the times in the semifinals.
Hint #33 / 3
Select this answer:
None of the above
DB should equal CB plus DC.
First write an expression to represent DC.
(x+168)-(3x+134)
x+168-3x-134
-2x+34
Then write an equal for DC plus CB equals DB
-2x+34+71= 153+2x
-2x+105= 153+2x
-4x+105=153
-4x=48
x= -12
Now plug in the value of x to find DB
153+2(-12)
153-24
129
Final answer: 129
Answer:
If the function is , the domain are all values of x greater than or equal to -6
If the function is , the domain are all values of x greater than or equal to 1
Step-by-step explanation:
First case
we have
we know that
The radicand of the function must be greater than or equal to zero
so
the solution is the interval---------> [-6,∞)
therefore
The domain are all values of x greater than or equal to -6
Second case
we have
so
we know that
The radicand of the function must be greater than or equal to zero
so
the solution is the interval---------> [1,∞)
therefore
The domain are all values of x greater than or equal 1
