The equation y = 26.2x represents the number of miles y Conrad runs in x marathons. Determine if there is a constant of variatio
WARRIOR [948]

Answer:

Yes, there is a constant of variation

Step-by-step explanation:

Let's see, we have a linear equation that is as follows:

<em>y = 26.2 * x. </em>

The first thing is to say that there is a constant of variation and it is the constant number of the equation, that is 26.2. And second to mention that it is the reason (or quantity, whether proportional or direct) for which the input data (i.e. x) and the output data (i.e. y) vary.

⅓(2x-4)+5=-⅔(x+1)<br><br><br>HALP
Kay [80]

\frac{2}{3} x -  \frac{4}{3}  + 5 =  \frac{ - 2}{3} x -  \frac{2}{3 }  \\  \frac{2}{3} x -  \frac{11}{3}  =  -  \frac{2}{3} x -  \frac{2}{3}  \\ 2x + 11 =  - 2x - 2 \\ 4x =  - 13 \\ x =  \frac{ - 13}{4}
