Radda [10]3 years ago
4 0

Answer:

10 units

Step-by-step explanation:

given coordinate points are:

(2,9)=(x1 , y1)

(8,1)=(x2 , y2)

distance between the points = \sqrt{(x2-x1)^2 + (y2-y1)^2}

=\sqrt{(8-2)^2 + (1-9)^2}

=\sqrt{6^2 + (-8)^2

=\sqrt{36 + 64

=\sqrt{100

=10 units

A small bag of trail mix contains 3 cups of dried fruit and 4 cups of almonds. A large bag contains 4 1/2 cups of dried fruit an
Nesterboy [21]

Answer:

The system don't have a unique solution

Step-by-step explanation:

We define the problem in different variables:

Dried Fruit is going to be x

Almonds are going to be y

So, in this new terms we have that a small bag (S) and a large bag ( L) are going to be represented by:

  1.      3x+4y=S
  2.      4\frac{1}{2}x+6y=L

If we multiply both sides of the first equation by 1.5 we got this:

  1.      4\frac{1}{2}x+6y=1.5S
  2.      4\frac{1}{2}x+6y=L

Therefore we can notice that the system of equations has an unlimited number of soltions because is a consistent and dependent system.

Which series of transformations results in the image being congruent to the pre-image?
erik [133]
For the element to be congruent only rotations, reflections or translations are allowed to be applied
1)
(x, y) → (x, –y)=reflection
(x, y) → (x + 5, y)=translation
(x, y) → (–x, y)=reflection
->is congruent
2)
(x, y) → (x + 1, y)=translation
(x, y) → (–x, –y)=reflection
(x, y) → (2x, y)=scaling->can't be congruent
3)
(x, y) → (0.5x, 0.5y)=scaling->can't be congruent
(x, y) → (x, –y)
(x, y) → (x, y + 8)
4)
(x, y) → (x – 4, y)=translation
(x, y) → (x, y + 3)=translation
(x, y) → (3x, 3y)=scaling->can't be congruent

so 1) is the only series of transformations with a congruent solution
