Answer:

4th Option / Graph is correct.

Step-by-step explanation:

We are given 4 graphs.

We need to find the graph of the parent Reciprocal Function.

Parent Reciprocal Function is defined as

f(x)=\frac{1}{x}

Domain of this function  = { x : x ∈ R and x ≠ 0 }

Co-Domain of the function = R

Range of the function = { x : x ∈ R and x ≠ 0 }

When we draw the function on graph we get a shape of Hyperbola.

Graph of this function is attached.

Therefore, 4th Option / Graph is correct.

Which linear inequality is represented by the graph?
aksik [14]

Answer:

B. y ≤ 1/2x + 3

Step-by-step explanation:

To write the equation of the inequality, use the linear equation form y = mx + b. The y-intercept is b and is where the line intersects the y-axis. Here b = 3. You can find the slope m by counting between points the vertical and horizontal distances. Here it is 1/2. Substitute m = 1/2 and b = 3.

y = 1/2x + 3

Since this is an inequality and a solid line has been used, you must use ≤ and ≥. To determine which is for this equation, test the point (0,0) in each.

y ≤ 1/2x + 3                y ≥ 1/2x + 3

0 ≤ 1/2(0) + 3             0 ≥ 1/2(0) + 3

0 ≤ 3  True               0 ≥ 3 False

Since (0,0) is a part of the set of solutions, the equation which is true is the correct equation.

Caroline, Colin & Sarah share some money.
Alex787 [66]

Caroline, Colin & Sarah share some money.Caroline will get \dfrac{2}{3}  when Caroline, Colin & Sarah share some money.

<h3>What is the ratio?</h3>

The ratio defined as the sharing of the two or three things or it represent that one thing or number is how many times to the other.

One part is excluded in the problem. That part is:

"Caroline gets \dfrac{1}{9} of the money."

If Caroline gets 1/9th, then remaining is:

1-\dfrac{1}{9}=\dfrac{8}{9}

Colin and Sarah share in ratio 3 is to 1, that means 3 + 1 = 4 parts...

8/9th in 4 parts means, each part is:

\dfrac{\dfrac{8}{9}}{4}=\dfrac{2}{9}

We know Colin gets "3" parts of the total, each part is (2/9)th, so 3 parts would be:

3\times \dfrac{2}{9}=\dfrac{6}{9}=\dfrac{2}{3}

Colin gets  \dfrac{2}{3} money when three of them share money.

What is Intercept of functions?
ICE Princess25 [194]
We have the Y-Intercept and the X-Intercept
The Y-Intercept implies that the X variable is set to zero and the X-Intercept implies that the Y variable is set to zero when solving equations of a line.

Which of the following is the conjugate of a complex number with 2 as the real part and 7 as the imaginary part?
MissTica

Answer:

2-7i is the correct option.

Step-by-step explanation:

We have been given the complex number real part 2 and imaginary part 7 it can be expressed as:

2+7i

And the conjugate means in the complex number is opposite sign of imaginary part that is in general:

a+ib will have conjugate a-ib

So, the conjugate of 2+7i is 2-7i

Hence, Option d is correct.
