Prove or disprove that point (4.00, 4.50) lies on circle O centered at the origin.

(4.0 , 4.5) to the center is not the distance of radius

Step-by-step explanation:

circle formula centered at origin: x² + y² = r²

x² + y² = 6² = 36

(4)² + (4.5)² = 16 + 20.25 = 36.25 ≠ 36

answer: d. $20

step-by-step explanation:

just took the test

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
