Triangle a is rotated 180° counterclockwise about the origin. which figure is the transformed figure? plz ill mark u as brainlies

B

Step-by-step explanation:

When you rotate a figure 180° counterclockwise or clockwise, you get the same result, the effect you get on each point you rotate is

(x′, y′) = (-x, -y)

You can look at the triangle as 3 points, A(1, -3), B(3, -1) and C(3, -5)

So the new points using the previous formula would be

A′ = (-1, 3)

B′ = (-3, 1)

C′ = (-3, 5)

so the answer is option B

B

Step-by-step explanation:

Under a counter clockwise rotation about the origin of 180°

a point (x, y ) → (- x, - y )

Consider the coordinates of the vertices of triangle A

(3, - 1 ) → (- 3, 1 )

(- 3, 5 ) → (- 3, 5 )

(1, - 3 ) → (- 1, 3 )

The image coordinates match those of Triangle B

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3

it's 100

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

  n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the  14th  row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
