3x+y=6

3x+y=6 is the new equation that has exactly one solution in common with Elena's equation. .A equation is said to have exactly one solution with this, if the set of equations meet at a point, or have a unique point of intersection. This only happens when the coefficient of x and the coefficient of y are different in the new equation. Solving these pair of equations gives us (1,2) as a unique point.

6x+2y=8

6x+2y=8 is the new equation which has no solutions in common with Elena's equation. An equation is said to have no solutions when the coefficients of both x and y are the same but the constant is different.

6x+2y=12

6x+2y=12 is the equation that has infinitely many solutions in common with Elena's equation. An equation is said to have infinitely many solutions if the result will be 0=0.

What is 1/4x+1+3/4x-2/3-1/2x

Aleks04 [339]

Answer: 1/2x + 1/3

Step-by-step explanation:

Given:

1/4(x) + 3/4(x) - 1/2(x) + 1 - 2/3

Step 1: Combine like terms

1/4(x) and 3/4(x) have a common denominator of 4. This means that you can add them together.

1/4(x) + 3/4(x) = 4/4(x) = x

Step 2: Find the common denominator of x in step 1 and combine like terms

x - 1/2(x) = 2/2(x) - 1/2(x)

Now that we have the common denominator of x, we can combine like terms. Its the same as adding or subtracting fractions without a variable. In this case, you must subtract 1/2(x) from 2/2(x).

2/2(x) - 1/2(x) = 1/2(x)

Step 3: Find the common denominator of the constants and combine like terms

1 - 2/3 = 3/3 - 2/3

Now combine like terms. Simply subtract 2/3 from 3/3.

3/3 - 2/3 = 1/3

Step 4: Write the simplified equation

1/2(x) + 1/3

This is the answer

Which complex number is represented by the graph

Dmitrij [34]

Answer:

$3-4i$

Step-by-step explanation:

The x-axis represents $x$ and $x$ is 3. The y-axis represents $iy$ and $y$ is -4 so $iy$ is -4i.

I know that real numbers consist of the natural or counting numbers, whole numbers, integers, rational numbers and irrational nu

ra1l [238]

The imaginary unit $i$ belongs to the set of complex numbers, denoted by $\mathbb C$ . These numbers take the form $a+bi$ , where $a,b$ are any real numbers.

The set of real numbers, $\mathbb R$ , is a subset of $\mathbb C$ , where each number in $\mathbb R$ can be obtained by taking $b=0$ and letting $a$ be any real number.

But any number in $\mathbb C$ with non-zero imaginary part is not a real number. This includes $i$ .

"is it possible that i can use an imaginary number for a real number"

I'm not sure what you mean by this part of your question. It is possible to represent any real number as a complex number, but not a purely imaginary one. All real numbers are complex, but not all complex numbers are real. For example, 2 is real and complex because $2=2+0i$ .

There are some operations that you can carry out on purely imaginary numbers to get a purely real number. A famous example is raising $i$ to the $i$ -th power. Since $i=e^{i\pi/2}$ , we have
