Which ordered pair represents the solution to the system of linear equations shown above? * (0, 2)
(5,0)
O (2,3)
O (3, 2)

(2,3)

Step-by-step explanation:

-x +5 =1/2x +2

-x - 1/2x = 2-5

-3/2x = - 3

-3/2x ÷ - 3/2 = - 3 ÷ -3/2

x= 2

Substitute x=2 in any equation

y= -(2) + 5

y= 3

Points are (2,3)

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.
