Number 10 is d and i’ll try 9 give me a minute lol
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
It is very simple, <span>|2x + 4| > 14, we have 2x+4>14 or -(2x+4) >14 (absolute value definition) so 2x> 14-4, x>10/2=5 or -2x>14+4, -x>18/2=9, implies x< - 9
the solution is x>5, or x< -9, so the answer is </span>number line with open circles on _9 and 5, shading going in the opposite directions.
Answer:
x=7
Step-by-step explanation:
8x-5y=16
8x-40=16
8x=56
x=7
Answer:
Step-by-step explanation: I'm assuming this problem says 56 divided by 7 times 2 in the numerator; OVER 4 to the second power in the denominator. First step would be to multiply 7 times 2, giving you 14. Thus u have 56 divided 14, which is 4. In the denominator, it says 4 to the second power, which is 16. Now u have 4 OVER 16. Now we will reduce the fraction. Both numerator and denominator have a GCF of 4. So we divide top and bottom number by 4. The end result is 1 OVER 4.
