Which graph shows a dilation

Answer:

e

Step-by-step explanation:

e

Answer:

The scale factor is 3

Step-by-step explanation:

Dilations

A dilation is a transformation that produces an image that has the same shape as the original but has a different size.  

A dilation is described by the scale factor or constant of dilation and the center of the dilation.

We are given a triangle XYZ of coordinates given in the graph to the left:

X=(-1,1), Y=(-1,4), Z=(-2,1)

It was dilated to triangle X'Y'Z' with coordinates:

X'=(-3,3), Y=(-3,12), Z=(-6,3)

Note each coordinate of the dilated triangle is three times the coordinates of the original triangle, thus the scale factor is 3

Answer:

4b +3r

The student did not subtract both terms in the second parentheses

Step-by-step explanation:

(6b + 4r) – (2b + r)

Distribute the minus sign to all terms in the second parentheses

6b + 4r – 2b - r

Combine like terms

6b -2b   +4r -r

4b +3r

The student did not subtract both terms in the second parentheses

Answer:

4b+3r

Step-by-step explanation:

(6b+4r)-(2b+r)

Distribute the negative symbol across the second set of parenthesis.

6b+4r-2b-r

Add like terms

4b+3r

Error: the student added r instead of subtracting it. They most likely only distributed the negative to the 2b.

Step-by-step explanation:

[tex] \frac{1}{3 } - \frac{2y}{9} = 19 \\ \frac{3 - 2y}{9} = \frac{171}{9} \\ 3 - 2y = 171 \\ 2y = 3 - 171 \\ 2y = - 168 \\ y = - 168 \div 2 \\ y = - 84[/tex]

Answer: y = − 84

Step-by-step explanation:

Simplify 5(3y−1)−3(2y)

9y=24

divide by each term by 9

y=-84

The answer is $32.74.

$3.75+$3.99+$12.50+$12.50 is $32.74.

Answer:

  (x +3)(x -3)(x +2i)(x -2i)

Step-by-step explanation:

The factoring to quadratics makes use of the fact that -36 = (-9)(4).

  x^4 -5x^2 -36

  = x^4 -9x^2 +4x^2 -36

  = x^2(x^2 -9) +4(x^2 -9)

  = (x^2 +4)(x^2 -9)

The form for factoring the difference of squares comes into play here. Of course -4 = (2i)^2.

  = (x^2 -(2i)^2)(x^2 -3^2)

  = (x -2i)(x +2i)(x -3)(x +3) . . . factored to linear terms

Answer:

[tex]\displaystyle y + 9 = \frac{16}{13} ( x + 6 )[/tex]

Step-by-step explanation:

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Where m is the slope and (h,k) is a point through which the line passes.

Given a line passes through points A(x1,y1) and B(x2,y2), the slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

We are given the points (-6,-9) and (7,7), thus the slope is:

[tex]\displaystyle m=\frac{7+9}{7+6}=\frac{16}{13}[/tex]

Now we apply the point-slope formula using the point (-6,-9):

[tex]\mathbf{\displaystyle y + 9 = \frac{16}{13} ( x + 6 )}[/tex]

This equation is expressed in the required format

The equation of the line passing through the given points is required.

The equation of the line is [tex]y=\dfrac{16}{13}x-\dfrac{21}{13}[/tex]

The points are [tex](-6,-9)[/tex] and [tex](7,7)[/tex]

The equation is

[tex]y-y_1=\dfrac{\Delta y}{\Delta x}(x-x_1)\\\Rightarrow y+9=\dfrac{7+9}{7+6}(x+6)\\\Rightarrow y+9=\dfrac{16}{13}x+\dfrac{96}{13}\\\Rightarrow y=\dfrac{16}{13}x-\dfrac{21}{13}[/tex]

The equation of the line is [tex]y=\dfrac{16}{13}x-\dfrac{21}{13}[/tex]

Answer:

6^6 = 46656

Step-by-step explanation:

I’m assuming your saying: 6^2 · 6^4, which is equivalent to 6^6 because if two numbers have the same base (in this case it’s 6), then you just add the exponents: add the exponents 2 + 4 = 6  ⇒  6^6

6^6 = 46656

Answer:

13x=2(5x+3)

13x=10x+6

13x-10x=6

3x=6

x= 6/3

x=2

Answer:

x=2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

13x=2(5x+3)

13x=(2)(5x)+(2)(3)(Distribute)

13x=10x+6

Step 2: Subtract 10x from both sides.

13x−10x=10x+6−10x

3x=6

Step 3: Divide both sides by 3.

3x/3=6/3

Answer:

[tex]2*2^{-3} * 2^{-5} =\frac{1}{128}[/tex]

Step-by-step explanation:

Given

[tex]2*2^{-3} * 2^{-5}[/tex]

Required

Write as a fraction

To do this, Jordan has to apply the following rules

Negative Exponent rule:

[tex]a^{-m} = \frac{1}{a^m}[/tex]

So, the expression is:

[tex]2*2^{-3} * 2^{-5} = \frac{2}{2^3 * 2^5}[/tex]

To solve further, we apply the product rule of exponent

[tex]a^m * a^n = a^{m+n}[/tex]

So, the expression is:

[tex]2*2^{-3} * 2^{-5} =\frac{2}{2^{3+5}}[/tex]

[tex]2*2^{-3} * 2^{-5} =\frac{2}{2^8}[/tex]

Evaluate the exponents

[tex]2*2^{-3} * 2^{-5} =\frac{2}{256}[/tex]

Divide the numerator and denominator by 2

[tex]2*2^{-3} * 2^{-5} =\frac{2/2}{256/2}[/tex]

[tex]2*2^{-3} * 2^{-5} =\frac{1}{128}[/tex]

Answer: 120

Step-by-step explanation:

2 = 240

240 / 2 = 120

unit = per

so the answer will be 120 calories

Answer:

2:240 or 2/240, whichever you like better. If you need a single unit answer, you would just divide this rate shown by 2 in order to get 1/120 or 1:120

Step-by-step explanation:

Every single part of the chart adds the first number. 2+2=4+2=6+2=8

Same thing with the bottom, 240+240=480+240=720+240=960.

The unit rate would be 2/240 by that logic, because for every 2 servings there are 240 calories.

When you divide it you get x+5.

Answer:

(x - 2)(x + 5)

Step-by-step explanation:

                    x   +5

          ----------------------

  x - 2 | x² + 3x - 10

This is because if u look closely you can see that all of these escept the (3,2) will be on the square. Hope this helps

1 foot = 12 inches.

Convert the dimensions of the region to inches:

2 feet = 24 inches

5 feet = 60 inches

Area of region = 24 x 60 = 1,440 sq. In.

Area of tile = 3 x 4 = 12 sq. In.

Number of tiles needed = 1440/12 = 120

120 tiles are needed.
