Which of the following is the best example of a system of equations that should be solved by the elimination method? Question 2 options:

8x + 3y = 2

5x + 8y = -11

2x - 4y = -16

y = 5x + 13

-8x - 9y = -17

16x - 4y = 12

12x + 7y = -17

9x + 11y = -7

the answer -8x-9y=-17

16x-4y=12

Step-by-step explanation:

divide 16x-4y=12 with 2

8x-2y=12

Then add the equations

-8x-9y=-17

8x-2y=12

0-11y=-23

You can’t do this with the other equations provided.

m∠vru = 80°

m∠urw = 15°

step-by-step explanation:

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
