X | y=2x+1
-3| -5
-2| a
-1| -1
0| b
1 | c
2| d

Replace x in the equation and solve for y:

a) y = 2(-2) +1 = -4 +1 = -3

b) y = 2(0) +1 = 0+1 = 1

c) y = 2(1) +1 = 2+1 = 3

d) y = 2(2) +1 = 4+1 = 5

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
