<span>(6+8i)(4-7i)
=6(4-7i)  + 8i(4-7i)
= (6)(4)-(6)(7i)+(8i)(4) - (8i)(7i)
= 24 - 42i + 32i - 56i^2
</span>= 24 - 42i + 32i - 56(-1)
= 24 - 42i + 32i + 56
= 24 +56 - 42i + 32i 
= 80 - 10i (final answer)

a system of equations has infinitely many solutions. if 2y – 4x = 6 is one of the equations, which could be the other equation?
deff fn [24]
<span>A system of equations has infinitely many solutions when the two lines representing the equations coincide. i.e. the two equations are the same or a multiple of each other.
2y - 4x = 6
2y = 4x + 6
2y = 2(2x + 3)
y = 2x + 3
-y = -(2x + 3)
-y = -2x - 3
Hence the other equation is -y = -2x - 3</span>
