use the subsitution method to slove the system of equations.Choose the correct ordered pair. x+3y=9 y=x-5

Answers

Answer 1
Answer : x= 6 , y=1
Explanation:
Answer 2

Answer:

(6, 1)

Step-by-step explanation:

We are given the equation for (y), [y=x-5]

So we can implement that in all the places the (y) are in the other equation.

x+3(x-5)=9

x+3x-15=9

add 15 to each side

4x=24

Divide each side by 4

x=6

Now we can apply our (x) into one of the equations.

y=(6)-5

y=1

So our solution is (6, 1)

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

Choose the expression that is equivalent to both −xy and x−y.

Answers

Answer:

x-y

Step-by-step explanation:

The expression which is equivalent to both -x/y and x/(-y) is the -1(x/y)  thus option (C) will be correct.

What is an expression?

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

An expression is a mathematical proof of the equality of two mathematical expressions.

As per the given expression,

-x/y and x/(-y)

If an expression is equivalent to both then both also must be the same.

Therefore, -x/y = x/(-y)

[(-1)x]/y = x/[(-1)y]

(-1)[x/y]= -x/y

Thus, -x/y = x/(-y) = (-1)[x/y]

Hence "The expression which is equivalent to both -x/y and x/(-y) is the -1(x/y) ".

Answer:

Multiplying a complex number by a real number

(x + yi) u = xu + yu i. In other words, you just multiply both parts of the complex number by the real number. For example, 2 times 3 + i is just 6 + 2i. Geometrically, when you double a complex number, just double the distance from the origin, 0.

binomial methods

Complex numbers use binomial methods of multiplication because unlike real numbers, imaginary numbers have two components.
