Determine whether ( – 4,3) is a solution of 2x – 2y = 0.

Mathematics
1 answer:
NemiM [27]3 years ago
5 0

Answer:

(-4,3) is NOT a solution of 2x-2y=0.

Step-by-step explanation:

First you substitute -4 and 3 for x and y in your equation.

2(-4) - 2(3) = 0

Then solve the equation

-8 - 6 = 0

-14 = 0

Since -14 cannot equal 0, (-4,3) is NOT a solution.

Use the compound interest formulas A = Pert and A = P(1+r/n)^nt to solve.
levacccp [35]
A = Pe^rt
P = 11,000 ; r = 6.25% ; t = 10 ; e = 2.7183 approximate

A = 11,000 e ^(0.0625 *10)
A = 11,000 e ^0.625
A = 11,000 * 2.7183^0.625
A = 11,000 * 1.868
A = 20,548

A = P (1 + r/n)^nt
P = 11,000 ; r = 6.3% ; n = 2 ; t = 10

A = 11,000 (1 + 0.063/2)^2*10
A = 11,000 (1 + 0.0315)^20
A = 11,000 (1.0315)^20
A = 11,000 (1.859)
A = 20,449
