The graph below shows the solution to a system of inequalities
which of the following inequalities is modeled by the graph?
a. x + 4y ≥ 15; y ≥ 0
b. x − 4y ≥ 15; y ≥ 0
c. x + 4y ≤ 15; y ≥ 0
d.−x − 4y ≥ 15; y ≥ 0

(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

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
