Answer: The missing side is 5 units.

Step-by-step explanation:

Pythagorean Theorem states that a^2+b^2=c^2.  Let the hypotenuse be x.

4^2+3^2=x^2\\16+9=x^2\\25=x^2\\\sqrt{25}=\sqrt{x^2}\\\left[\begin{array}{c}x=5\end{array}\right]

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.
