What is the algebraic rule for a figure that is rotated 270° clockwise about the origin? A. RO,–270°(x, y) → (–y, x) B. RO,–270°(x, y) → (x, –y) C. RO,270°(x, y) → (–x, –y) D. RO,270°(x, y) → (–y, –x) Please select the best answer from the choices provided A B C D

the answer is 24

step-by-step explanation:

16.80 times .20= 3.36

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

c
