Answer:

b) change the places of the numbers in the numerator and the denominator for the second fraction

Step-by-step explanation:

In the phrase "keep change flip":

You "keep" the first fraction.

"Change" the division sign into a multiplication sign.  

"Flip" (or switch) the places of the numerator and denominator in the second fraction.

Example:

[tex]\frac{1}{2}[/tex] ÷ [tex]\frac{1}{3}[/tex]

[tex]\frac{1}{2}*\frac{3}{1}=\frac{3}{2}=1.5[/tex]

Hope this helps.

Step-by-step explanation:

Answer:

(2,1)

Step-by-step explanation:

multiply by negative three on the first equation then solve

Answer:

(-2, 1)

Step-by-step explanation:

Given:

2x+8y=4...(1)

6x-y=-13...(2)

You would want to have an x or a y value that equals the same in both equations. In this case, we can multiply equation 1 by 3 so that both x's in each equation equal 6x.

(2x+8y=4) x 3...(1)

6x-y=-13...(2)

becomes...

6x+24y=12...(3)

6x-y=-13...(4)

As you can see here, both x's in this equation are equal.

Now we will be combining these equations together. Take the equal x values and make sure they will equal 0. You do that by either subtracting the entire equation or adding it. In this problem, we will be subtracting it because 6x-6x=0

(6x+24y=12) - (6x-y=-13) = 25y =25

Now that we can solve for y separately, 25y=25   y=1

To solve for x, just substitute y into one of the original equations (equations 1 or 2). For this problem, I'll use equation 1.

6x-y=-13

6x-1=-13

6x=-12

x=-2

The value of  8/9/20 could be either 0.04 or 17.77.

In such a fraction, the value that appears above the horizontal line is referred to as the numerator.

In another word, the fraction is the division of the two numbers but the division is not wholly complete.

In another word, if we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator.

It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.

Given the fraction,8/9/20

Case 01)

(8/9)/20 = 0.888/20 = 0.044.

Case 02)

8/(9/20) = 8/0.45 = 17.77.

Hence "The value of  8/9/20 could be either 0.04 or 17.77".

Answer:

So the slope is -2 while the y-intercept is -2

Step-by-step explanation:

y=mx+b

so you need to rearrange it so it will be

y=-2x-2

So m is slope so it is -2

and -2 is b which is the y-intercept so it is -2

Answer:

vertex B' is at (1, 1)

Step-by-step explanation:

Let us revise the rules of translation of a point

Let us use the rules to solve our question

∵ Vertex A = (-5, 2)

∵ Vertex A' = (2, -2)

→ The coordinates of the two points changed which means the

  quadrilateral is translated horizontally and vertically

∵ The x-coordinate of A = -5

∵ The x-coordinate of A' = 2

→ Which means it moves to the right, so use the first rule above

∴ the rule of translation is T (x, y) → (x + h, y)

∴ x → x + h

∵ x = -5 and x + h = 2

∴ -5 + h = 2

→ Add 5 to both sides

∴ -5 + 5 + h = 2 + 5

∴ h = 7

∴ The quadrilateral is translated 7 units right

∵ The y-coordinate of A = 2

∵ The y-coordinate of A' = -2

→ Which means it moves down, so use the 4th rule above

∴ the rule of translation is T (x, y) → (x, y - k)

∴ y → y - k

∵ y = 2 and y - k = -2

∴ 2 - k = -2

→ Add K to both sides

∴ 2 - k + k = -2 + k

∴ 2 = -2 + k

→ Add 2 to both sides

∴ 2 + 2 = -2 + 2 + k

∴ 4 = k

∴ The quadrilateral is translated 4 units down

→ Let us find B'

∵ T (x, y) → (x + h, y - k) is the rule of translation

∵ B = (-6, 5)

∵ h = 7 and k = 4

∴ B' = (-6 + 7, 5 - 4)

∴ B' = (1, 1)

∴ vertex B' is at (1, 1)

Quadrilateral ABCD is translated 7 units right and 4 units down. If vertex B is at (-6, 5), then vertex B′ is at (1, 1)

Answer:

The number 513 is called the numerator or dividend, and the number 19 is called the denominator or divisor.

The quotient of 513 and 19, the ratio of 513 and 19, as well as the fraction of 513 and 19 all mean (almost) the same: 513 divided by 19, often written as 513/19.

Step-by-step explanation:

Answer:

27

Step-by-step explanation:

First you set up the equation of your quotient. Then divide it by 19, like so 513÷19 lastly you solve the answer that the math you calculated.

Answer:

y = - [tex]\frac{1}{5}[/tex] x - 9

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

4x + 20y = - 180 ( subtract 4x from both sides )

20y = - 4x - 180 ( divide all terms by 20 )

y = [tex]\frac{-4}{20}[/tex] - [tex]\frac{180}{20}[/tex] , that is

y = - [tex]\frac{1}{5}[/tex] x - 9 ← in slope- intercept form

Answer: (7,2)

Step-by-step explanation below.

Hello!

First, we need to put it in the y2-y1/x2-x1 form.

8-1/4-2 = 7/2

So the slope would be...

m = 7/2

So the line would go up 7 and right 2.

Answer:

B

Step-by-step explanation:

I took the quiz.

Answer:

18

Step-by-step explanation:

w varies directly with z, let k be the constant of proportionality, hence this can be represented by the equation:

w = kz

When z = 4, w = 12, hence we need to find the value of the constant of proportionality, substituting:

12 = 4k

Dividing both sides by 4:

12/4 = 4k/4

k = 3

Therefore the equation becomes:

w = 3z

The value of w when z = 6 is given as:

w = 3(6)

w = 18

Answer:

The measured side is not shown, so i will answer in a general way.

A cube is a 3-dimensional object with 6 square faces.

You know that all the sides of a square have the same length, then is the same for the cube.

To calculate the volume of a cube, we start with the area of the base.

The base is a square of sidelength L (Suppose that L is the length of the measured side)

The area of the base is:

A = L^2.

To find the volume, we must multiply the area of the base by the height of the fire (because the section of the base does not change).

And the height of the cube is also L.

Then the volume is:

V = L*a = L^3
