Your answer is not correct.

The correct answer is the third one:

-No, because the distance from the origin to point (7,-7) is greater than the radius of the circle.

VARVARA [1.3K]

N = first integer
n + 1 = second integer
n + 2 = third
n + 3 = fourth

the sum is 114 so:

n + (n + 1) + (n + 2) + (n + 3) = 114

solve:

4n + 6 = 114
4n = 108
n = 27

so 27 is your first.
27 + 1 is your second (remember n +1 n +2 and n +3)

so your first four integers are: 27 28 29 and 30

week one: x
week two: x + 5
week three: 2(x+5) or 2x + 10

week1 + 2 + 3 = 431

so its:

x + (x+5) + (2x + 10)
4x + 15 = 431
4x = 416
x = 104

its then:

week one: 104 sold
week two: 109 sold (x + 5)
<span>week three: 218 (2x + 10)

I'm really not sure how to go about solving this algebraic equation, please help! .513 = (2x)^2 / (.05-x)

LiRa [457]

Let's set it up like this:
$0.513=\frac{\left(2x\right)^2}{\left(0.05-x\right)}$
Multiply both sides by $0.05-x$
$0.513\left(0.05-x\right)=\frac{\left(2x\right)^2}{0.05-x}\left(0.05-x\right)$
$0.513\left(0.05-x\right)=4x^2$
We are then going to use the distributive property. Since we also know that the opposite of an number that is squared is the square root, we can also apply that. We would be left with something like this:
$x=-\frac{0.513+\sqrt{0.673569}}{8},\:x=\frac{\sqrt{0.673569}-0.513}{8}$
The variable $x$ can be both positive or negative.
We have found successfully our answer.
