Tanzania [10]
\dfrac{3x+6}{x^2-x-6} +  \dfrac{2x}{x^2+x-12}

= \dfrac{3(x+2)}{(x + 2)(x - 3)} +  \dfrac{2x}{ (x - 3)(x + 4)}

= \dfrac{3}{(x - 3)} +  \dfrac{2x}{ (x -3)(x + 4)}

= \dfrac{3(x+4)}{(x - 3)(x + 4)} +  \dfrac{2x}{ (x -3 )(x + 4)}

= \dfrac{3(x+4) + 2x }{(x - 3)(x + 4)}

= \dfrac{3x+12 + 2x }{(x - 3)(x + 4)}

= \dfrac{5x+12}{(x - 3)(x + 4)}

Use two sets of coordinates to write an equation<br> to describe the relationship.
Irina-Kira [14]

Answer/Step-by-step explanation:

An equation that describes the relationship can be written as y = mx.

Using the two sets of coordinates, (2, 140) and (4, 280), calculate the slope (m) as shown below:

\frac{y_2 - y_1}{x_2 - x_1} = \frac{280 - 140}{4 - 2} = \frac{140}{2} = 70

Substitute m = 70 into y = mx

The equation would be:

y = 70x

This equation can be interpreted as follows:

The heart's resting rate is 70 beats each minute.
