Parallel lines have the same slope, so the slope of the new line is 1/2.
The line passes through (0,4), and this gives the y-intercept, which would equal 4.
The equation now would be: y = 1/2x + 4
Answer: Option B
Step-by-step explanation:
By definition, only those functions that are one to one have an inverse function.
A function is one by one if there are not two different input values,
and
, that have the same output value y
Note that the function
is not a one-to-one function
When x=2 
When x=8 
Note that the function
is not a one-to-one function
When x=1 
When x=-1 
Note that the function
is not a one-to-one function
When x=1 
When x=-1 
Then the answer is the option B.
You can verify that The function
is a one-to-one function and therefore its inverse is a function
Answer: C
Step-by-step explanation: With inverse equations, you switch y and x (y=f(x)) and undo/reverse the steps towards x.
1. Multiply by 3
2. Add 2
Equation by itself
0. x
1. 3(x)
2. 3(x+2)
Answer: inferential
Step-by-step explanation: inferential statistics help us to make predictions ( that is, inferences) from that data. With inferential statistics, you take data from samples and make generalizations about a population.
Also, inferential statistics allow us to reach conclusions that extend beyond the immediate data alone
In this question, the survey reports on a sample of the country's population that make an inference to the population. It is therefore an inference statement.
The correct answer is C) 800,000 cubic meters.
The scale given is for the length, width or height of the model. In order to find the scale for the volume, we would cube this scale, since volume is a cubic measurement:
(1/200)³ = 1/8,000,000
Since the volume of the model is 0.1, we multiply this by 8,000,000 to find the volume of the actual dam:
0.1(8000000) = 800,000
