Answer:

D. inverse variation; xy = 8

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

For direct variation the equation relating x and y is

y = kx, that is

k =  

Using the values in the table

= 2

=  

k is not constant hence not direct variation

For inverse variation the equation relating x and y is

y = , that is

k = xy

Using the values in the table

2 × 4 = 8

4 × 2 = 8

8 × 1 = 8

12 ×  = 8

Thus the table represents inverse variation with xy = 8

...............................................................................................................................................

Answer:

D. inverse variation; xy = 8​

Step-by-step explanation:

First we need to understand the concept of direct and inverse relation or proportion between variables.

When value of one variable increases with the increase in value of second variable, this relation is called directly proportional.

When value of one variable decreases with the increase in value of second variable, this relation is called inverse proportion.

You can observe it it daily life example too. Like if you pour water in glass, its weight will increase. If you add more water, the weight of glass will increase more. It is direct proportion. But on the other hand, if one man do any particular task in 2 hours, two men will perform task in less time, which means the hours of work are inversely proportional to number of men.

Now in given equation you can see that, when x = 2, y =4, but when x = 4, y =2, which means value of y is decreasing with the increase in value of x. So this relation is inverse.

You can also satisfy the equation by putting values of x and y.

xy = 8

From first column

2x4 = 8

From last column

12x(2/3) = 8

Graph the following equations in 4 different colors
marissa [1.9K]

The given equations are linear functions and represent straight lines.

The first equation F(x) = 2x , represent a straight line passing through the origin.

Now, we plot the rest equation using the transformation of the graph.

  • If we add a constant 'a' in the function then it gets shifted upward by 'a' units.
  • If we subtract a constant 'a' in the function then it gets shifted downward by 'a' units.

Using these properties, the second graph gets shifted upward by 6 units. Hence, it passes through (0,6)

Third graph will shift downward by 3 units. Hence, it passes through the point (0,-3)

Fourth graph will shift downward by 5 units. Hence, it passes through the point (0,-5)

The graph of these functions are shown in the same xy-plane in the attached file.

Find the values of x and y that satisfy the equation.<br>-10x+12i=20+3yi​
blondinia [14]

Answer:

x = -2

y = 4

Step-by-step explanation:

Given

-10x+12i=20+3yi

Two complex numbers are equal when they have equal real and imaginary parts.

Equate real parts:

-10x=20\\ \\x=-\dfrac{20}{10}=-2

Equate imaginary parts:

12=3y\\ \\y=\dfrac{12}{3}=4

Miss Jones it it it is Southern living home party to purchase a vase which cost $34.99 the shipping charge was three dollars and
creativ13 [48]

Answer:

The amount paid for the vase is <u>$41.12</u>.

Step-by-step explanation:

Given:

A vase which cost $34.99 the shipping charge was $3.00 and 8.25% sales tax was paid on the subtotal which including the shipping charge.

Now, to find the amount paid for the vase.

Cost of vase = $34.99.

Shipping charge = $3.00.

Sales tax = 8.25%.

So, on adding shipping charge on cost of vase:

34.99+3.00=\$37.99.

As, given sales tax was paid on the subtotal which including the shipping charge.

Now, to get the amount paid for the vase:

<em><u>$37.99 + 8.25% of $37.99</u></em>

<em><u /></em>=37.99+\frac{8.25}{100} \times 37.99<em><u /></em>

<em><u /></em>=37.99+0.0825\times 37.99<em><u /></em>

<em><u /></em>=37.99+3.13<em><u /></em>

<em><u /></em>=\$41.12.<em><u /></em>

Therefore, the amount paid for the vase is $41.12.
