Determine wether the equation represents a direct variation. If it does find the constant of variation. 2y=5x+1
svp [43]

Answer:

No, the equation does not represent a direct variation.

Step-by-step explanation:

The answer is immediately evident:  NO.  The reason for this is that no direct variation equation includes a vertical intercept.

Here 2y = 5x + 1 becoems y = (5/2)x + 1/2; the y-intercept 1/2 is problematic.

If we were to drop the constant 1, then 2y = 5x, or y = (5/2)x; this represents direct variation with the constant of proportionality 5/2.

Which products result in a difference of squares or a perfect square trinomial? check all that apply. (5x 3)(5x – 3) (7x 4)(7x 4
Scilla [17]

(7x + 4)(7x + 4) and (x – 9)(x – 9) are Perfect square trinomial. (5x + 3)(5x – 3) and (–3x – 6)(–3x + 6) shows the Difference of squares.

<h3>What is a perfect square?</h3>

A perfect square is a number system that can be expressed as the

square of a given number from the same system.

The following are the answers

(5x + 3)(5x – 3) Difference of squares

(7x + 4)(7x + 4) is a Perfect square trinomial

(2x + 1)(x + 2) has Neither a difference of squares nor a perfect square trinomial.

(4x – 6)(x + 8) has Neither a difference of squares nor a perfect square trinomial.

(x – 9)(x – 9) is Perfect square trinomial

(–3x – 6)(–3x + 6) = (-3x)^2- ( -6)^2  Difference of squares.

Let D = {xlx is a state in the United States} be the domain, and let f(x) - "the state capital" be the possible function. Determ
stepladder [879]

ANSWER

Yes, f is a function.

EXPLANATION

The domain of the relation is D = {xlx is a state in the United States}

The rule is that f(x) ="the state capital"

The relation will be a function if and only if no two elements in the first set have the same image in the second set.

Since no two states will have the same capital, the relation is a function.
