<span>Circle D circumscribes ABC and ABE, The statements that best describe the triangles are: 
</span><span>Statement I: The perpendicular bisectors of ABC intersect at the same point as those of ABE.
Statement II: The distance from C to D is the same as the distance from D to E. Hence, each of them (CD and DE) is a radius of the given circle.
So, the answer is the second option, I and II.

Nancy's mother has a large collection of footwear.
DiKsa [7]
I think A, C, D are right because of the 12 pairs of heels, 6 are black (6/12) That means half of them could be chosen and be black (0.5). Another way to write 0.5 is as a percentage, 50%.

Express the polar coordinates (2,3pi/4) as Cartesian coordinates
Rus_ich [418]

The Cartesian equivalent of the polar coordinates (r, theta) is

(r cos t, r sin t), where t = theta.

So, (2, 3pi/4) becomes

(2 cos(3pi/4), 2 sin(3pi/4))

(2 • -sqrt{2}/2, 2 • sqrt{2}/2)

Answer: (-sqrt{2}, sqrt{2})

Done.

Note: sqrt = square root for short.

Which system of equations is graphed below? On a coordinate plane, a line goes through (0, 1) and (4, negative 2) and another go
natulia [17]

Answer:

The correct option is (B)

(B) x-y = 6 , 3x+4y = 4

Step-by-step explanation:

As we can see in the graph given below, both lines intersect at (4, -2), which should be the solution of given equations:

Find the values of x and y for (B);

x - y = 6 ⇒ (i)

3x + 4y = 4 ⇒ (ii)

Lets consider equation (i)

x - y = 6

x = 6 + y

Substitute in equation (ii)

3(6+y) + 4y = 4

18 + 3y + 4y = 4

7y = -14

y = -2

Substitute in equation (i)

x - (-2) = 6

x + 2 = 6

x = 6 - 2

x = 4

As solution of part C is also (4, -2), it represents the graph

You can also find the (x, y) for other options the similar way, which will show you they don't have the same value
