Find all real zeros of the function y=2x -4.

a. 2
b. 2, -4
c. -4
d. -2​

step-by-step explanation:

10.50 + taxes which added up to 11.50

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

answer: .64
