Answer: last option.

Step-by-step explanation:

- Subtract the fractions that are in the numerator.

- Add the  fractions that are in the denominator.

Then:

\frac{\frac{1}{x}-\frac{1}{y}}{\frac{1}{x}+\frac{1}{y}}=\frac{\frac{y-x}{xy}}{\frac{y+x}{xy}}

- Multiply the numerator of the fraction on the top by the denomianator of the fraction on the bottom.

- Simplify.

Then:

=\frac{(y-x)(xy)}{(y+x)(xy)}=\frac{(y-x)}{(y+x)}

Answer:

The correct answer is last option

Step-by-step explanation:

It is given that,

(1/x - 1/y)/(1/x +1/y)

<u>To simplify (1/x - 1/y)</u>

1/x - 1/y = (y - x)/xy

<u>To simplify (1/x - 1/y)</u>

1/x + 1/y = (y + x)/xy

To find equivalent expression

(1/x - 1/y)/(1/x +1/y = [(y - x)/xy]/[(y + x)/xy]

 = (y - x)*xy/(y +x)*xy = (y - x)/(y + x)

Therefore the correct answer is last option

\boxed {D}


EXPLANATION


The given function is,

g(x) = ⌈x + 3⌉

The parent function of this ceiling function is

g(x) = ⌈x ⌉

When this function is shifted horizontally 3 units to the left, we obtain the transformed function,

g(x) = ⌈x + 3⌉


The correct answer is option D.

the line is on <em>x=5</em>

the line is whole so it is less or greater than and equal to

the shaded part is to the left, so it is less than

So, the inequality represented by the graph is x≤5
