I'm assuming that you mean x^2 (x squared), so correct me if I am wrong.
So, to get "x" by itself, you need to square root both sides to do this. This will produce x = 9.27, in which, rounded to the nearest tenth, x approximately = 9.3.
Answer:
Strictly speaking, there is not enough information to solve the problem.
If we assume m<EFY = 90, then:
m<DEY = 29
m<DEF = 58
Step-by-step explanation:
Going by the exact information shown, the answer is really that there isn't enough information to answer the question.
On the other hand, if angle EFY is a right angle, then we have two right triangles that can be proved congruent by HL. Then by CPCTC, angles DEY and FEY are congruent. We set their measures equal and solve for y.
4y - 7 = 2y + 11
2y = 18
y = 9
m<DEY = 4y - 7 = 4(9) - 7 = 36 - 7 = 29
m<DEF = 2m<DEY = 2(29) = 58
In science, density is the amount of mass per unit volume. Similarly, in economics, population density is the amount of population per unit area. That will be our basis in answering the questions for this problem.
Since there is no diagram given, I can't distinguish which island is in the left or right. I'll just assume that the first island is on the left, while the second island is on the right. Assuming they have the same population, the density would only have to matter with the area. From the given definition of population density, we write it in equation as:
Density = Population/Area
So if the area is large, the density would consequently be smaller. Therefore, you can see in the equation that density and area are inversely proportional to each other. We can deduce that the first island with the smaller land area of 486 mi² has a greater population density. When a place has a smaller area, the population density is much greater. Therefore, the answer to #1 is left, the answer to #2 is smaller, and the answer to #3 is more.
The answer would be B. I think...but I'm not sure. Hope this helps!
Answer:
y=-3x+5
Step-by-step explanation:
y-y1=m(x-x1)
y-5=-3(x-0)
y-5=-3(x)
y-5=-3x
y=-3x+5
