She can make 75 cakes with 15 cups of flour
Line through P(0, 5) and Q(-1, 8):
slope = m = (y2 - y1) / (x2 - x1) = (8 - 5) / (-1 - 0) = 3 / -1 = -3
line through R(3, 3) and S(5, -1):
slope = m = (y2 - y1) / (x2 - x1) = (-1 - 3) / (5 - 3) = -4 / 2 = -2
Parallel lines have equal slopes. Since the two lines have different slopes, they are not parallel.
8X3 equals 24
3x 8 equals 24
Eight rows of 3 =24
3 rows of 8 = 24
B. A worker with 40 hours of training is paid $1700 per month.
-6 - 3(5y + 4)
= - 6 - 15y -12
= -15y - 18
Hope it helped!
