The midpoint of SR is M(5,-2). One endpoint is S(-1,3). Find the coordinates of endpoint R.
A. R(11,–7)
B. R(2, 1)
C. R(
6-5)
D. R(2,0.5)
wer 1.

The answer is A

Step-by-step explanation:

Midpoint formula:  (x1 + x2) / 2, (y1 + y2) / 2

In this case, we already have the midpoint, so one of the x and one of the y values are unknown, whereas the sum is not.

(-1 + x) / 2 = 5, (3 + y) / 2 = -2

For both equations multiply both sides by 2

-1 + x = 10, 3 + y = -4

x = 11, y = -7

Rewrite as coordinates.

(11, -7)

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
