Use the points (1, 15000) and (8, 1000) for the slope of the trendline
m = (1000 - 15000)/(8 - 1) = (-14000)/7 = -2000
y = -2000x + b
15000 = -2000(1) + b
15000 = -2000 + b
17000 = b
Equation
y = -2000x + 17000
To round a number to the nearest thousands, we will check the number is the hundreds position:
if the number in the hundreds position is smaller than 5, then we will convert all numbers after the thousands position to zeroes
if the number in the thousands position is equal to or greater than 5, we will add one to the thousands and convert all digits after it to zeroes.
The number we have is <span>2,042,822
Applying the above concept we will find that:
the number in the hundreds position is 8 which is greater than 5
Therefore:
</span>2,042,822 to the nearest thousands is <span>2,043,000</span>
First find the slope:
(-3-2)/(0-2)=-5/-2=5/2
So then y=5/2x+b
When x=0, then the y-coordinate with that is the y-intercept.
So the answer is y=5/2x-3.
Assume a statement true and then show it must be false.

Answer:
7(45)=7(40)+7(5)
Step-by-step explanation:
We need to represent 7(45) using the distributive property to simplify.
We can write 45 as 40+5
So it becomes,
7(45) = 7(40+5)
Distributive property is : a(b+c)=ab+ac
a=7, b = 40 and c = 5
7(40+5)=7(40)+7(5)
So, the correct option is (4).
