Is there a commutative property of subtraction that states a-b=b-a? investigate and make a conclusion that you justify.
Rom4ik [11]

No is your answer

Assuming that b ≠ a, the answers will not be the same.

For example, (remembering that b ≠ a) let us assume that b = 10, a = 5

10 - 5 = 5

5 - 10 = -5

5 ≠ -5

So the commutative property of subtraction does not work unless in certain cases, in which a = b.

hope this helps

At the end of 2​ years, P dollars invested at an interest rate r compounded annually increases to an​ amount, A​ dollars, given
postnew [5]

The interest rate will be equal to 24% in 2 years.

<h3>What is compound interest?</h3>

Compound interest is the interest levied on the interest. The formula for the calculation of compound interest is given as:-

Given that:-

  • Find the interest rate if ​$32 increased to ​$50 in 2 years.

The interest rate will be calculated by using the following formula:-

A = P[1+\dfrac{r}{n}]^{nt}

50=32[1+\dfrac{r}{1}]^{2}

\dfrac{50}{32}=(1+r)^2

1.56 = ( 1 + r )²

√1.56 = ( 1 + r )

r = 1.24 - 1

r = 0.24

r = 24%

Therefore  interest rate will be equal to 24% in 2 years.
