Grace and lily have a diferent point of view about the transformation on cube that is shown above.
grace states that it is a reflection about the imaginary axis and a dilation of factor of 2. however, lily argues it
should be a 90° counterclockwise rotation about the origin with a dilation of a factor of 2.
a. who is corect? justify your answer.
b. represent the above transformation in the form l(x, y) = (aa− b, b+ aa).

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

i dont know

step-by-step explanation:

umm. i dont know

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
