Solve the given linear Diophantine equation. A) 12x+9y=15 B) 8x+10y=17
Nookie1986 [14]

Answer:

  A) (x, y) = (2-3n, 4n-1) . . . . for any integer n

  B) no solution

Step-by-step explanation:

A) All coefficients have a common factor of 3, so any solution of the reduced equation will be a solution of the given equation. The reduced equation is ...

  4x +3y = 5

A graph of the original shows (x, y) = (2, -1) is a solution. Then other solutions will be those values with a multiple of 4 added to y and the same multiple of 3 subtracted from x:

  (x, y) = (2 -3n, 4n -1)

__

B) The left side of the equation is an even number for any integer values of x and y. The right side is an odd number. There can be no solution.

Minerva starts a savings account with $50. The interest on the account balance is compounded annually. The graph below shows the
rodikova [14]

We can set up this equation using this formula:

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

p = starting amount.

r = interest.

n = number of times it's compounded in a year

t = years

We'd set it up like this:

a = 50(1 + ?/1)^1(12)

Because we're missing the amount of interest, it would be impossible to tell what the amount would be after 12 years.
