STEPS TO GET THE CORRECT ANSWER:

First write your question like this:
{ ( [9x] [-31/8] ) - ( [7x] [+13/8] ) }

2: You need to subtract 9x and 7x from (9x-31/8)-(7x+13/8) you get 2x. So now you know that the answer has 2x. Eleminate A) and D).

3: Then need to subtract -31/8 from +13/8. You get -11/2.
Turn -11/2 into a mixed number you will get -5 1/2.

4: Put 2x and -5 1/2 together and you would get 2x-5 1/2

But answer C.) is closest to 2x-5 1/2 so the answer is

ANSWER: C.) 2x-4 1/2

Points C and D lie on circle O as shown below. If OC = 6x+2 and OD = 10x -16, then find the length of the radius of circle O.
Ket [755]
Radius = OC = OD

Solve for x:

10x -16 = 6x+2

4x = 18

x = 9/2 = 4.5

Sub 'x' back into OC

OC = 6(4.5) + 2 = 29

Radius = 29

Plug in (7, 12) for x and y in the equation.

12 = 2(7) + 1
12 = 14 + 1
12 ≠ 15 

Therefore, (7, 12) is not on the straight line equation.
