Cos(60) = cos(90 - 30) = sin(30) = 1/2
This should be what you want.
"<em>The product of 8 and a number increased by 4 is 60" </em>can be written as:
8y + 4 = 60
Your answer is A.
First subtract the x variable on both sides so on the first equation youll have -6y=8x+60 then divide 6 on all variables which means youll have y=8/6x+10 and in the second equation you do the same thing and youll have y=-5/6x-11.5
Wait just a minute. Hold up. Hee haw. Whoa !
Coming down to Earth for just a second ... what in the world is
the "distance" between integers anyway !
