Find an ordered pair to represent a in the equation a = 2b + c if b = (6,3) and c = (-4,8)

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)
