Question

andre’s resting heart rate
$y = -3x + 76$
maya’s resting heart rate
maya starts out at a resting heart rate of 80 bpm, and it decreases by 2 beats per minute each week leading up to the tournament.
answer each question based on the given representations.
what was andre’s initial resting heart rate (at week 0)?
______ beats per minute
what was maya’s initial resting heart rate (at week 0)?
______ beats per minute
who started out with the faster resting heart rate (at week 0)?
______

Explanation:

Step1: Encontrar la tasa inicial de André

La ecuación de la tasa cardíaca en reposo de André es \( y = -3x + 76 \). En la semana 0 (\( x = 0 \)), sustituimos \( x \) por 0: \( y = -3(0) + 76 = 76 \).

Step2: Encontrar la tasa inicial de Maya

Se dice que Maya comienza con una tasa cardíaca en reposo de 80 bpm en la semana 0.

Step3: Comparar las tasas iniciales

André tiene 76 bpm y Maya tiene 80 bpm. Entonces, Maya comenzó con la tasa cardíaca en reposo más rápida.

Answer:

• André's initial resting heart rate: 76 beats per minute
• Maya's initial resting heart rate: 80 beats per minute
• Who started with the faster resting heart rate: Maya
