I am not sure but I would say either step 2 or 4 but I am not 100% sure I hope you do well. Good Luck:)
X>44
.25(x)-3-4>4

Answer:
Step-by-step explanation:
first we need to find the slope using the slope formula :
slope = (y2 - y1) / (x2 - x1)
(-9,7)...x1 = -9 and y1 = 7
(-6,-3)....x2 = -6 and y2 = -3
now we sub
slope = (-3 - 7) / (-6 - (-9) = -10 / (-6 + 9) = -10 / 3
so our slope is -10/3
now we use y = mx + b....with m representing the slope
slope(m) = -10/3
use either of ur points....I will use (-9,7)...x = -9 and y = 7
we are solving for b, the y intercept
now we sub
7 = -10/3(-9) + b
7 = 30 + b
7 - 30 = b
- 23 = b
so ur equation is : y = -10/3x - 23
Answer:

Step-by-step explanation:
We are told that the average human heart beats
times per day and there are
days in one year.
To find number of heart beats in one year we will multiply number of heart beats in one day by number of days in one year.

Now we will solve this problem using exponent properties.



Our answer is in scientific notation we can represent it in standard form as
times.
Therefore, average human heart beats in one year
or 41975000 times.
