Symbol... X... Negative y, , , , ,

Answers

Answer:

D. (x, y) → (x, −y)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

The orientation shows how an object is arranged. Rotation, translation and dilation preserves orientation while reflection does not preserve orientation.

The transformation (x, y) → (4x, 4y) shows the dilation by a scale factor of 4. Dilation preserve orientation.

The transformation (x, y) → (−y, x) shows the rotation of a point 90 degrees counterclockwise. Rotation preserve orientation.

The transformation (x, y) → (14x, 14y) shows the dilation by a scale factor of 14. Dilation preserve orientation.

The transformation (x, y) → (x, −y) shows a reflection over the x axis. Reflection does not preserve orientation.

Determine if the side lengths given form a triangle. Justify your response. 6.4 mm, 12.9 mm, 14.2 mm

Answers

Answer:

Step-by-step explanation: Yes I think since if you add 12.4 and 6.4 your answer is more then 14.2 so yes it is possible

Answer:

Yes, it does form a triangle

Step-by-step explanation:

According to the first triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third side. This means that the given side lengths DO form a triangle. 6.4+12.9=19.3 which is more than 14.2.

Slope:

No choices solve on own

Answers

Answer:

y - intercept: 3/4

slope: -5/4

Step-by-step explanation:

put into slope-intercept form first, y = -5/4x + 3/4

then you can see that the slope and y - intercept are -5/4 and 3/4

Answer:

The answer for the y-intercept is (0, -3/4). The answer for the slope is -5/4.

Step-by-step explanation:

You know this because you must pull the 4 out of the equation, along with the y, so it is -4y=5x+3. You would put both of these numbers over 4: (5 and 3). A positive number which is 5, divided by a negative gives you negative so you can just say -5/4. Same with +3/-4. You can change it to -3/4, because positive over negative equals negative answer.

Answer:

Step-by-step explanation:

p= 9

Answer:

p=9

Step-by-step explanation:

8*4p+8*5

32p+8*5

32p+40

8(5p-4)

multiply the numbers:8*5=40

8*5p-8*4

Multiply the number 8*4=32

40p-8*4

40p-32

32p+40=40p-32

Subtract 40p from both sides:

32+40-40=40p-32-40

Simplify:

-8p=-72

divide both sides by: -8

-8p/-8=-27/-8

p=9

the total number of possible salads you could create?
35
3600
150
900

Answers

Answer:

3600

Step-by-step explanation:

multiply all of the choices

10x15x6x4

The total number of possible salads you could create is 3600. so the correct option is B.

What is the fundamental principle of multiplication?

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

WE have been given the following choices: 10 dressings, 15 vegetables, 6 cheese toppings and 4 different crouton toppings.

Therefore, the total number of possible salads you could create;

Then multiply all of the choices

10 x 15 x 6 x 4

= 3600

Hence, The total number of possible salads you could create is 3600. so the correct option is B.
