Answer:
a. 2/3 or 0.6666...
b. AB = 6cm and AD = 3cm
Step-by-step explanation:
28/42 = 2/3
14/21 = 2/3
42*1/7 = 6
21*1/7 = 3
Answer:
The ordered pair to represent a in the equation a=2b+c if b=(6,3) and c=(-4,8) is: a=(8,14)
Step-by-step explanation:
b=(6,3)
c=(-4,8)
a=2b+c
Replacing b and c in the equation above:
a=2(6,3)+(-4,8)
Multiplying:
a=(2*6,2*3)+(-4,8)
a=(12,6)+(-4,8)
Adding:
a=(12+(-4),6+8)
a=(12-4,14)
a=(8,14)
Perpendicular because when graphed, it creates a cross, or an intersection at a 90 degree angle
