Answer:
x = 10
Step-by-step explanation:
The marked sides are proportional, so we have ...
x/8 = (x +5)/12
3x = 2(x +5) . . . . . multiply by 24 to clear fractions
3x = 2x + 10 . . . . . eliminate parentheses
x = 10 . . . . . . . . . . subtract 2x
_____
<em>Alternate solution</em>
We observe that the difference between the upper segment lengths is ...
(x +5) -(x) = 5
and the difference between the lower segment lengths is ...
12 -8 = 4
This means the upper segment lengths are 5/4 times as long as the lower segments. Then ...
x = (5/4)(8) = 10

Answer:
The confidence level is 95% or 0.95.
Step-by-step explanation:
Consider the provided information.
Results of a poll stated that 40% of U.S.
If you want to test the claim at alpha = 0.05.
As we know:
Confidence level = 1 - significance level (
)
Confidence level = 
Confidence level = 
Therefore, the confidence level is 95% or 0.95.
Answer: D. y = x^2
Step-by-step explanation:
Linear functions are functions in which the power of the unknown variable is 1 , that is the other of the unknown variable will be 1
A. y = x
This is a linear function because both x and y has 1 has their power
B. y = 2x
This is also linear
C. y = x + 2
This is also linear
D. y = x^2
This is not linear , although the power of y is 1 but the power of x is 2 , for it to be linear , the highest power of the unknown must be 1
