Answer: d.) 3.6x + 6.1
Step-by-step explanation:
Combine like terms
6.4x + 3.1 + (-2.8x) + 3
(6.4x - 2.8x) + (3.1 + 3)
3.6x + 6.1
Answer:
78.94
Step-by-step explanation:
It's the circle of life yeah yeah and it moves us all.
we know that
the rate of a linear equation is equal to the slope
Step 1
Find the bear’s average heart rate when it’s active
Let
A(1.5,90) B ( 2,120)
the slope is equal to
m=(y2-y1)/(x2-x1)
m=(120-90)/(2-1.5)=30/0.5
m=60 heartbeats/min
therefore
the answer part a) is
the bear’s average heart rate when it’s active is 60 heartbeats/min
Step 2
Find the bear’s average heart rate when it’s hibernating
Let
A(1.5,18) B ( 2,24)
the slope is equal to
m=(y2-y1)/(x2-x1)
m=(24-18)/(2-1.5)=6/0.5
m=12 heartbeats/min
therefore
the answer part b) is
the bear’s average heart rate when it’s hibernating is 12 heartbeats/min
11, 3, -3, -12
