Answer:

Step-by-step explanation:

To determine if the point (- 3, 5) is a solution to both equations.

Substitute the x and y values into the left side of both equations and if equal to the right sides then the point is a solution.

x - 3y = - 3 - 3(5) = - 3 - 15 = - 18 ← True

- 2x + y = - 2(- 3) + 5 = 6 + 5 = 11 ← False

Thus (- 3, 5) is not a solution to the system of equations.

Solve for x^2-2x+1=0

seraphim [82]

Answer:

$x=1$

Step-by-step explanation:

$x^2-2x+1=0\\$

We will start by using the quadratic formula.

$\frac{-(-2)+-\sqrt{(-2)^2-4(1)(1)}}{2(1)}$

We will simplify that and get:

$\frac{-(-2)}{2(1)}$

So our answers would be:

$x=1$

Convert 2000 Swiss francs to Dutch guilders

Shtirlitz [24]

Answer:

2000 swiss francs equals 3920 Dutch Guilders!

Step-by-step explanation:

One Swiss Franc equals 1.96 Dutch Guilders. Having said this, we can come up with the following equation:

D = 1.96S

Where 'S' represents the swiss francs and 'D' the Dutch Guilders. Now, to convert 2000 Swiss francs, we just need to plug the value into the equation:

D = 1.96(2000) = 3920

So, 2000 swiss francs equals 3920 Dutch Guilders!
