Answer:
1×-5= -5squared =25+(4×-4squared)=25+(-16)=9
So each of these statements are talking about the square footage of land per person. Let's go and find it!
First off, let's find the number in each building of the original complex:
280 people / 4 buildings
Each building has an equal number of residents. So just divide:
280/4 = 70.
So 70 residents per building
Now consider the fact that once a new building is built, another 70 people will move in.
280 + 70= 350
350 people total.
Then lets look at the plot of land
Originally, there are 200,000 square feet of land for the 4 buildings. Then after the expansion, the plot of land will be:
200,000 + 200*200
= 200,400
Go back to the question. What's the effect of the expansion in terms of square feet of land per person?
Divide!
200,400 / 350
Approximately = 572.57 square feet
Then since it's being compared to the amount each resident had before the expansion, do the same thing with the corresponding numbers:
200,000 / 280
Approximately = 714.29
So how much will each person's land decrease?
714.29 - 572.57 approximately = 141.72 square feet.
The answer is the first choice!

Step-by-step explanation:
-9(2)-(-6)(2)+3(-20)
(−9)(2)−(−6)(2)+(3)(−20)
=−18−(−6)(2)+(3)(−20)
=−18−(−12)+(3)(−20)
=−6+(3)(−20)
=−6+−60
=−66
Answer:
V=706.85
Step-by-step explanation:
Well, first of when you want to find the volume of the cone you need to have a radius and hieght. And the radius is half the diameter, so divide the diameter into half: 10/2=5 in. and you already have the height so just plug in the numbers.
Formula: V= 
h ---> V= (
)(27)
And put the plugged in formula in your calculator and you'll find the answer!
V=706.85

Answer & Step-by-step explanation:
7. The slope-intercept form of a linear equation is y = mx+b where m is the slope and b is the y-intercept. Looking at the two equations, we can rearrange them to be
y = -8x+1
y = 8x+2
From this, we can see that the m, or slope, of the equations are -8 and 8 respectively. Thus, we can determine that the steepness of both equations are equal though one is pointed downwards and the other upwards.
8. We already know that m is the slope so if the function is increasing, the slope is going upwards, thus m must be larger than 0.
Next, we plug in (4,0) into the function to determine b.
f(x) = mx + b
0 = m(4) + b
Since we have determined that m is larger than 0 and thus a positive number, m*4 will be a positive number. The only way for m(4) + b to equal to 0 then is for b to be a negative number, smaller than 0.
