How I can answer this question, NO LINKS, If you answer correctly I will give u brainliest!

The Y-intercept: (0,12)

The X-intercept: (4,0)

y - intercept (0, 12)

x - intercept (4,0)

Step-by-step explanation:

Y intercept means the x-coordinate is 0

X intercept means the y-coordinate is 0

y-intercept (0, 12)

Plug in, y = -3*0 +12

y = 0 +12

y = 12

x - intercept (4,0)

0 = -3x + 12

Minus 12 on both sides

-12 = -3x

x = 4

go on the tube you might find some information there

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
