Which of the following equations are equations of a direct variation? Choose all that apply.
(a) x=−2y
(b) x+2y=12
(c) 3x−2y=0
(d) 5x^2+y=0
(e) y =0.3x +1.6
(f) y−2=x

Answers

Answer:

(a) x = -2y

Step-by-step explanation:

You can tell if an equation is a direct variation equation if it can be written in the format y = kx.

Note that there is no addition and subtraction in this equation.

Let's put these equations in the form y = kx.

(a) x = -2y

y = x/-2 → y = -1/2x This is equivalent to multiplying x by -1/2, so this is an example of direct variation.

(b) x + 2y = 12

2y = 12 - x y = 6 - 1/2x This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.

-2y = -3x y = 3/2x This follows the format of y = kx, so it is an example of direct variation.

(d) 5x² + y = 0

y = -5x²This is not in the form of y = kx, so it is NOT an example of direct variation.

(e) y = 0.3x + 1.6

1.6 is being added to 0.3x, so it is NOT an example of direct variation.

(f) y - 2 = x

y = x + 2 2 is being added to x, so it is NOT an example of direct variation.

The following equations are examples of direct variation:

x = -2y 3x - 2y = 0

Answer:

(a) x = -2y

Step-by-step explanation:

You can tell if an equation is a direct variation equation if it can be written in the format y = kx.

Note that there is no addition and subtraction in this equation.

Let's put these equations in the form y = kx.

(a) x = -2y

y = x/-2 → y = -1/2x

This is equivalent to multiplying x by -1/2, so this is an example of direct variation.

(b) x + 2y = 12

2y = 12 - x

y = 6 - 1/2x

This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.

-2y = -3x

y = 3/2x

This follows the format of y = kx, so it is an example of direct variation.

(d) 5x² + y = 0

y = -5x²

This is not in the form of y = kx, so it is NOT an example of direct variation.

(e) y = 0.3x + 1.6

1.6 is being added to 0.3x, so it is NOT an example of direct variation.

(f) y - 2 = x

y = x + 2

2 is being added to x, so it is NOT an example of direct variation.

The following equations are examples of direct variation:

x = -2y

3x - 2y = 0

Max car holds 18 gallons of gasoline driving on the highway the car uses approximately 2 gallons per hour. let H represent the number of hours max has been riding on the highway. write an expression that shows how many gallons of gasoline Max has left after driving H hours. then find the number after max drives 3.5 hours on the highway.

Answers

y= 18 gallons-2(h)
y is what you're trying to find out and since there are 18 gallons in the tank after every hour you would have 2 less gallons. So, you can multiply how many hours he's been driving by the 2 gallons and subtract it from 18

Step-by-step explanation:

To find out the area of this irregular figure, divide it into two rectangles and add their areas.. This can be done in two ways.

Version 1: 6 * 2 rectangle and 3 * 3 square

(6 * 2) + (3 * 3)

12 + 9

21 sq. ft.

Version 2: 5 * 3 rectangle + 2 * 3 rectangle

(5 * 3) + (2 * 3)

You could really just do 7 * 3 here.

7 * 3

21 sq. ft.

Either way, you still get 21 square feet as your answer.

21 = w^2 + 4w

C.
21 = w^2 – 4w

D.
21 = w^2 + 4

Answers

Answer:

Step-by-step explanation:

The equation to determine the length and width of the rug is 21 = w² + 4w.

What is Rectangle?

A rectangle is a four sided figure with opposite sides are equal .

Area of a rectangle = Length x width

Given that A rectangular rug with an area of 21 square feet.

The rug is 4 feet longer than it is wide.

Let 'l " be the length of the rug and 'w' be the width of the rug

Length is 4 feet longer than its width

l = w + 4

Area is 21 square feet.

Area = l x w

21 = (w + 4)w

21 = w² + 4w

The equation to determine the length and width of the rug is 21 = w² + 4w.

So width is 3 ft

Length = w +4

length = 3+4= 7 feet

Thus Length of the rug is 7 feet

Length of rug = 7 feet

width of the rug = 4 feet
