Answer:
C. x+8=3x
Step by step explanation:
First, subtract 8 from both sides of the equation
x+8=3x
x+8-8=3x-8
Then, simplify it by subtracting again
x+8-8=3x-8
x=3x-8
Then, subtract 3x from both sides of the equation
x=3x-8
x-3x=3x-8-3x
Then, simplify by combining the terms
x-3x=3x-8-3x
-2x=3x-8-3x
-2x=3x-8-3x
-2x= -8
Then, divide both sides of the equation by the same term
-2x= -8
-2x/-2 = -8/-2
Then, simplify by cancling terms that are in both the numerator and denominator
-2x/-2 = -8/-2
x= -8/-2
Finally, divide the numbers
x= -8/-2
x=4
And that's your answer! :)
Answer:
Step-by-step explanation:
Definition of an absolute value is:
<em>1).</em> Assume that (y + 2) ≥ 0, then
y + 2 > 6 ⇒ <em>y > 4</em>
<em>2).</em> Now, if (y + 2) < 0, then
- (y + 2) > 6 ⇔ - y - 2 > 6 ⇒ <em>y < - 8</em>
<em>y ∈ ( - ∞ , - 8) ∪ (4 , ∞ )</em>
Answer:
even
Step-by-step explanation:
An even function is symmetrical about the y- axis.
The graph of the function given is symmetrical about the t- axis and is therefore even.
Answer:

And for this case that represent the 5.6% of the homeless persons who are veterans
Step-by-step explanation:
We know that in a survey of 250 homeless persons 14 were veterans. We can find the estimated proportion of homeless persons who are veterans with the following formula:

The last one is an unbiased estimator of the true population proportion p
And replacing the info given we got:
