Answer:
15%?
Step-by-step explanation:
sorry if im wrong
To determine the equation of the line, we use the point slope form equation for this problem. It is expressed as:
y - y1 = m(x - x1)
We substitute the given values in the problem to the equation.
y - 2 = -5(x - 2)
y = -5x +10+2
y = -5x +12
Answer:
$30444.41
Step-by-step explanation:
→ Work out compound interest
(100 + 6) ÷ 100 = 1.06
→ Multiply the amount by the money
17000 × 1.06
→ Find how many years it is for
17000 × 1.06¹⁰ = 30444.41
