Answer:
A canary's heart beats around 1,000 times per minute or 16.67 times per second. A canary is a very small bird whose heart beats more than twelve times faster than yours.
While a bat's heart beats between 200 to 1,000 times per minute. That means that while the bat is flying, its heart beats at the same rate as a canary's. But when the bat is resting, its heart beats is reduced by 5 times to "only" 200 beats per minute or 3.33 beats per second.

"The graph below" is an important source of information here. In fact, you
actually can't answer the question without it. That's a big part of the reason
it was printed right there in the same place you copied the question from.
6x - y = 31 so y = 6x - 31
substitute y = 6x - 31 into 3x + 7y = 8
3x + 7y = 8
3x + 7(6x - 31) = 8
3x + 42x -217 = 8
45x = 225
x = 5
y = 6x - 31
y = 6(5) - 31
y = 30 - 31
y = -1
answer
x = 5 and y = -1
