Which of the following equations is an example of inverse variation between the variables x and y

Sonbull [250]

Answer:

The answer is y = 6/x ⇒ answer A

Step-by-step explanation:

* Lets revise what is the meaning of the inverse variation

- It is a mathematical relationship between two variables

- It can be expressed by an equation in which the product of two

variables is equal to a constant

- If y is in inverse variation with x

∴ y ∝ 1/x

- Change this relation to equation

∴ y = k/x, where k is the constant of the variation

- We can write it by another way

∵ y ∝ 1/x

∴ y = k/x ⇒ by using cross multiplication

∴ yx = k

* Now lets solve the problem

∵ There is an inverse variation between the two variables x and y

∴ y ∝ 1/x

∴ y = k/x

- Look to the answer

# We will chose A because

∵ y = 6/x ⇒ use the cross multiplication

∴ yx = 6 ⇒ and 6 is a constant

∴ k = 6

* The answer is y = 6/x

Dare to solve it so easy ☺️

Answer: 1.23×10¹⁶

Step-by-step explanation:

For this problem, we want to use order of operations to solve.

Parenthesis

Exponent

Multiply

Divide

Add

Subtract

Let's first solve the parenthesis.

$(9*\frac{999999999}{9+9+9+9+9+9+9+9+9} )^2$ [add denominator]

$(9*\frac{999999999}{81} )^2$ [cross multiply]

$(\frac{999999999}{9} )^2$ [divide]

$(111111111)^2$ [exponent]

1.23×10¹⁶

The ending result is way too large. Therefore, we use scientific notation and get 1.23×10¹⁶.

A truck that can carry no more than 7100 lb is being used to transport refrigerators and upright pianos. Each refrigerator weigh

pishuonlain [190]

Let x be the number of refrigerators

Y be the number of pianos

So the inequality:

300x + 475y < 7100

So substitute 12 and 8 to the inequality

300(12) + 475(8) < 7100

3600 + 3800 < 7100

7400 < 7100 is not true

So it will overload the truck
