Answer:

Only natural numbers (i.e., non-negative integers) can be the exponents of variables in a polynomial.

Step-by-step explanation:

The exponent of variables in a polynomial should be natural numbers ( $0$ , $1$ , $2$ , $3$ , $\dots$ .)

$\sqrt{2\, x}$ is equal to $\sqrt{2}\, x^{1/2}$ . In this expression, $x$ is the variable. Its exponent is $1/2$ , which isn't a natural number.

On the other hand, $\sqrt{2}\, x$ is equivalent to $\sqrt{2}\, x^{1}$ . The exponent of variable $x$ is $1$ , which is indeed a natural number.

$\sqrt{2\, x}$ isn't a polynomial because the exponent of variable $x$ isn't a natural number. On the other hand, $\sqrt{2}\, x$ is indeed a polynomial over the set of real numbers.

Help me out asap!please and thank you

Answer:

c. (5, -2)

Step-by-step explanation:

as we can clearly see, the 4th vertex has to be on the positive side of x.

therefore, all answer options with negative x are out.

(2, -5) is almost at D (-1, 5). that cannot be right for a rectangle.

that leaves only c as right answer.

FYI - how to get this without predefined answer portions ?

the x- difference of B to A is 4 (from -5 to -1). the x-difference from D to C must be the same (4). 1 + 4 = 5.

so, x of D must be 5.

the y- difference of B to A is 3 (from 3 to 6). the y-difference from D to C must be the same (3). -5 + 3 = -2.

so, y of D must be -2.

Factor the following polynomial. ( Correct and best explained answer gets brainliest. )

Glad you asked this question! Over the years of working with my professor we learned that if phs= 5 (constant) times the j to the power of 2 you will get the formula or polynomialic equation. It quite fascinating and due to using his equation the answer in fact is "c". Cheers

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

2x + y = 3

-2x + 5y = -9

Step 2: Solve for y

Elimination

Combine equations: 6y = -6
Divide 6 on both sides: y = -1

Step 3: Solve for x

Define equation: 2x + y = 3
Substitute in y: 2x - 1 = 3
Isolate y term: 2x = 4
Isolate y: x = 2
