It would be: $60.00 - ($46.42+$21.05)
$60.00 - $67.47 = -$7.47
Answer:
Step-by-step explanation:
Hint: 1 - Cos² A = Sin² A
E3, E6, E11, E7: no solution
E1, E12 : 1 solution
E2, E8, E10 : infinite solutions
A' ( 2, 4) and B' ( -4, 0)
A ( -2, 4) and B( 4,0) reflected over the y-axis
the y-coordinate do not change and the x is opposite sign
(x,y) reflected over y-axis (-x, y)
