The value of an investment is expected to grow by 5% per year. how long will it take for the value to double?

about 4 years
about 7 years
about 14 years
about 23 years

It will take about 14 years  for the value to double.

Step-by-step explanation:

Hi, to answer this question we have to apply the rule of 72.

To estimate the doubling time we have to divide 72 by the interest rate in percentage form, which in this case is 5%.

Mathematically speaking:

72/ 5 =14.4 =about 14 years

It will take about 14 years for the value to double.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
