Answer:

no real solutions

complex solutions: x = 0.5±i√10.75, y = -2.5±i·3√10.75

Step-by-step explanation:

The graph shows the line and parabola do not intersect, so there are no real solutions to this system of equations.

However, the complex x-solutions can be determined from the graph to be ...

x = 0.5 ±i√10.75

The corresponding y-values can be found from the equation

y = 3x -4 = 3(0.5 ±i√10.75) -4

y = -2.5 ± i·3√10.75

Mary deposits R400 every three months into a bank account earning interest at 16% per year, compounded quarterly. The approximat

ycow [4]

Answer:

The approximate time that it will take Mary to save R40000 is 29 years

Step-by-step explanation:

A= p(1+r/n)^nt

t = log(A/P) / n[log(1 + r/n)]

A = R40000

n = 4

P = R400

r = 16%

t = log(A/P) / n[log(1 + r/n)]

= log(40,000 / 400) / 4{log(1+0.16/4)}

= log(100) / 4{log(1+0.04)}

= 2 / 4{log(1.04)}

= 2 / 4(0.0170)

= 2 / 0.068

= 29.41

t = 29.41 years

Approximately 29 years

The approximate time that it will take Mary to save R40000 is 29 years
