Look at the function f(x) = −x + 5. Which of the following describes the domain and range of the function and its inverse?
Answers
Answer:
the first
0 5
5 0
Step-by-step explanation:
the question should be : "which describes a POSSIBLE domain and range definition of the function and is inverse ?"
because this is just a matter of definition. the function itself would not suggest any limits.
and in that regard the function definition is basically irrelevant.
the domain of any basic function is the range of the inverse, and the range of the basic function is the domain of the inverse.
so, the second set of definitions is not possible, if we are really trying to define the inverse function.

solve the literal equation for y.
Answers
Answer:
2B / (mx) = y
Step-by-step explanation:
B = 1/2 mxy
Multiply each side by 2
2B = 2* 1/2 mxy
2B = mxy
Divide each side by mx
2B / (mx) = mxy / (mx)
2B / (mx) = y
Answer:
[tex] \huge y = \frac{2B}{mx} \\ [/tex]
Step-by-step explanation:
[tex]B = \frac{1}{2} mxy \\ [/tex]
Multiply through by 2 to eliminate the fraction
That's
[tex]mxy = 2B[/tex]
Divide both sides by mx to make y stand alone
We have
[tex] \frac{mxy}{mx} = \frac{2B}{mx} \\ [/tex]
We have the final answer as
[tex]y = \frac{2B}{mx} \\ [/tex]

under the same denominator r(r-4)
[6(r-4)] / (r(r-4)) + (4r) / (r(r-4)) = 1
(6r - 24 + 4r) / (r(r-4)) = 1
10r - 24 = r (r-4)
10r - 24 = r² - 4r
r² - 14r + 24 = 0

Use vector operations to draw the resultant vector.
b) Draw 2u – 1 /3 v.
Answers
Vectors are elements of the vector space, and they can be illustrated by diagrams.
How to draw the vector 2u - 1/3vThe vector expression is given as:
2u - 1/3 v
Split the vector expressions, as follows:
[tex]y_1 = 2u[/tex]
[tex]y_2 = -\frac13v[/tex]
See attachment for the graphs of y1 and y2.
Next, we have:
[tex]y = 2u - \frac13v[/tex]
So, we have:
[tex]y = y_1 + y_2[/tex]
The above expression means that, we add the vectors y1 and y2 to get vector y
See attachment for the graph of 2u - 1/3 v
