In Exercises 7 graph JKL with vertices J(3, 1), K(4,2), and L(1, 3) and its image after the glide reflection. translation: (x, y) (x-6,y-1) reflection: in the line y=-x

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

: )

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
