Answer:
increase
Step-by-step explanation:
The rate at which you burn calories is called your metabolic rate. During exercise, you not only increase metabolism in your muscles but also in your respiratory and circulatory systems. You need a faster rate of breathing and heart rate to deliver oxygen and nutrients to your muscles.
Step-by-step explanation:
Let the first number be <em>x</em>
Let the second number be <em>y</em>
<em>x</em> = y - 9
3x = 4y + 12
3x - 4y = 12
3(y - 9) - 4y = 12
3y -4y - 27 = 12
-y = 12 + 27
-y = 39
y = -39
x = y - 9
x = -39 - 9 = -48
