Suppose that x and y vary inversely, and x = 7 and y=11. Which function models the inverse variation?Answers:Y=1.57xY=77/xY=4/xY
sdas [7]

Answer:

Y=77/x

Explanation:

Y varies inversely with x meaning

y\propto\frac{1}{x}

adding a proportionality constant gives

y\propto\frac{k}{x}

Now, we are told that y = 11 and x = 7; therefore, the above gives

11=\frac{k}{7}

Solving for k gives

k=77

Therefore, the function that models the inverse variation is

y=\frac{77}{x}

which is our answer!

Jarvis left out a statement from the proof shown.which statement is best explained by the corresponding angles postulate
Salsk061 [2.6K]
The postulate of the corresponding angles establishes that when a transversal line cuts two parallel lines, the corresponding angles are congruent. These angles are on the same side of the parallel lines and on the same side of the transversal line.

  Then, if we based on this definition and analize the figure attached, we can notice that the angles ∠1 and ∠3 are corresponding angles, so they are congruent. In this case the angle ∠1 is internal and the angle ∠3 is external.

 The answer is: ∠1 and ∠3 are congruent (See the image attached).

Inga [223]

Answer:

g(x) = \frac{x+3}{x-3}

Step-by-step explanation:

From the picture attached,

Given function is,

f(x) = x + 1

We have to find the value of g(x) if the composite function has been given as,

f[g(x)] = g(x) + 1 = \frac{2x}{(x-3)}

g(x) = \frac{2x}{(x-3)}-1

      = \frac{2x-(x-3)}{(x-3)}

      = \frac{(x+3)}{(x-3)}

Therefore, g(x) = \frac{x+3}{x-3} will be the answer.
