Given f = 9 5 c + 32, the conversion formula for fahrenheit to celsius, solve for c. a) c = 5 9 (f - 32) b) c = 9 5 (f - 32) c) c = 9 5 · f 32 d) c = 5 9 · f 32

20 da is equal to a. 2,000 cm. b. 2 m. c. 20,000 cm. d. 20,000 mm

Lena reflected this figure across the x-axis. she writes the vertices of the image as a'(−2, 8), b'(−5, 6), c'(−8, 8), d'(−4, 2).
