What type of dilation is formed when the scale factor K is greater than one

Answers

Answer:

Enlargement

Step-by-step explanation:

When k > 1, the dilation is an enlargement. When k > 0 and k < 1, the dilation is a reduction. In a dilation, the original figure and its image are similar. The ratio of the side lengths of the image to the corresponding side lengths of the original figure is the scale factor of the dilation.

It is true because 3/6 is that smallest fraction or "simplest form" of 6/12

Step-by-step explanation:

6/12 does simplify to 3/6 because if you divide 2 by 6 and 12 you’ll get 3 and 6, and you cannot simplify 3/6 further.

the answer above is correct

Type an equation for the
following pattern.

y=[? ]x+[ ]

Answers

y = -x + 6

To solve for the slope, choose two pairs of coordinates and substitute their values into the slope formula.

Let (x1, y1) = (1, 5)
(x2, y2) = (2, 4)

m = (y2 - y1)/(x2 - x1)

m = (4 - 5)/(2 - 1)
m = -1/1
m = - 1
Therefore, the slope, m = -1.

For the y-intercept, choose one of the given points, and use it along with the slope to solve for the y-intercept. Using point (2, 4) and the slope, m = -1, substitute their values into the slope-intercept form:

y = mx + b
4 = -1(2) + b
4 = -2 + b

Add 2 to both sides to solve for b:
4 + 2 = -2 + 2 + b
6 = b

Therefore, the linear equation is :

y = -x + 6

Step by step explanation:

The question asks which one has the lowest unit price. The key word is unit, not just what is shown on the chart. You have to divide the price by the number of ounces to get the price for one ounce(unit). Then you look at all the prices and whichever one is the lowest is the answer. These are the unti prices after you divide the price by the number of oz

Graph the linear equation 5x-4y < 20

Answers

using a graphing calculator:

Answer: (See attached image file)

Step-by-step explanation:

Start by plotting given key features

Based on the problem, we know that the x-intercept is (0,4) We find this by plugging in 0 for y, and solving for x (5x = 20)(x = 20/5 = 4) (4, 0)

We can also easily solve for the y-intercept, which is (0,-5)We find this by plugging in 0 for x, and solving for y(-4y = 20)(y = -5) (0, -5)

Since we know that the equation is linear, seeing as the highest exponent is 1, we know that these two points have to be connected by a single, straight line.

Finally, we shade in the side to the LEFT of the line. This is because the equation asks for LESS THAN. If however the question had been 5x-4y>20, we would shade in the region to the right.

PLS HELP DUE IN 10 min

Answers

Answer: y= -3x + 16

Step-by-step explanation:

I'm assuming that you mean a linear equation

So the first thing that you want to do is find the slope for the line.

1-(-2) / -3 - 6= -9/3= -3

Now that you have the slope you can pick one of the points to plug in.

-2 = -3(6) + b

We don't know what the y intercept is so we'll need to solve for that.

-2= -18 + b

add -18 to -2

16=b

so your equation will be

y= -3x + 16

A line passes through the points (0, 9) and (9, 19). What is its equation in slope-intercept form?

Answers

Answer:

y = 10/9x + 9

Step-by-step explanation:

To write the equation in its slope-intercept form, y = mx + b, we need to find the slope (m) of the line and its y-intercept (b).

Given the points (0, 9) and (9, 19), we can solve for the slope of the line using the following formula:

[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

Let (x1, y1) = (0, 9)

and (x2, y2) = (9, 19)

Substitute these values on the formula:

[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{19 - 9}{9 - 0} = \frac{10}{9}[/tex]

Therefore, the slope (m ) = 10/9.

Next, the y-intercept is the point on the graph where it crosses the y-axis, and has the coordinates, (0, b ). It is also the value of the y when x = 0.

One of the given points is the y-intercept of the line, given by (0, 9). The y-coordinate, 9, is the value of b.

Therefore, the linear equation in slope-intercept form is: y = 10/9x + 9

Find the measure of the marked angles.
The measure of the angles is
___ degrees

Answers

Answer:

43°

(4x + 19)° = (6x + 7)° [vertically opposite angles are equal]

4x+19 = 6x+7

4x + 19 -7 = 6x

4x +12 = 6x

12 = 6x - 4x

12 = 2x

2x = 12

x = 12/2

x = 6

Now replace the x with 6

(4x+19)°

= (4×6+19)°

= (24+19)°

= 43°

(6x+7)°

= (6×6+7)°

= (36+7)°

= 43°

The measure of the angles is 43 degrees

Al simplificar la expresión -3(a – b) + 5b – {2a + b + [a – 3b – (2b – a) + 5b] – a}, se obtiene:

Answers

Al simplificar la expresión-3 (a - b) + 5b - {2a + b + [a - 3b - (2b - a) + 5b] - a}, se obtiene: - (6a + 7b)

La simplificación de expresiones algebraicas requiere la eliminación de los corchetes por sus factores de multiplicación seguido de la combinación y agrupación de los términos semejantes en suma y resta.

De la información proporcionada:

= -3 (a - b) + 5b - {2a + b + [a - 3b - (2b -a) + 5b] - a}

El primer paso es abrir los soportes de adentro hacia afuera.

i.e.

= -3a + 3b + 5b - {2a + b + [ a - 3b - 2b + a + 5b] - a}= - 3a + 3b + 5b - {2a + b + a - 3b - 2b + a + 5b - a}= - 3a + 3b + 5b -2a - b - a + 3b + 2b - a -5b + a

Ahora, el siguiente paso es la reorganización;

= - 3a - 2a - a - a + a + 3b + 5b - b + 3b + 2b - 5b= - 6a - 7b

Por factorización;

= - (6a + 7b)

Por tanto, podemos concluir que la simplificación de la expresión anterior es - (6a + 7b).

Your friend calculates the distance between points Q(1,5) and R(3,8), as shown below. What is his error?

Answers

The distance between two points is the number of units between them.

The distance between Q and R is 3.61 units

It is impossible to determine your friend's error, because the steps are not given in the question. So, I will calculate the distance between Q and R, instead.

The distance (d) between two points is:

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

So, the distance QR is:

[tex]QR = \sqrt{(1 - 3)^2 + (5 - 8)^2}[/tex]

[tex]QR = \sqrt{(- 2)^2 + (- 3)^2}[/tex]

Evaluate exponents

[tex]QR = \sqrt{4 +9}[/tex]

[tex]QR = \sqrt{13}[/tex]

Take square root of 13

[tex]QR = 3.61[/tex]

Hence, the distance between Q and R is 3.61 units
