Make it into slope intercept form
-3y = -12x + 3
Y = 4x - 1
Perpendicular = opposite sign and reciprocal
Parallel: same slope
Perpendicular: y = -1/4x
Parallel: y = 4x
100 x 5= 500 ($)
50 x 5= 250 ($)
40 x 5=200($)
so, she needs to sell min. 40 and mac. 100 cakes to reach her goal.
correct answer is b. 40_< x >_100
It's 21 square units. If you map it on a complex plane (x-axis is real numbers, y-axis is imaginary numbers) you'll see that the sides of the rectangle is 3 and 7 which multiply to 21.
