Question

v ( x ) =12-2x-5 when x= -2,0,5 solve step by step

Answer 1

v(-2) = 11,  v(0) = 7,  v(5) = -3.

hope this helps! :)

$v(x) = 12 - 2x - 5\\v(-2) = 12 - 2(-2) - 5\\v(-2) = 12 + 4 - 5\\v(-2) = 11\\-----------------------------\\v(0) = 12 - 2(0) - 5\\v(0) = 12 - 0 -5\\v(0) = 7\\-----------------------------\\v(5) = 12 - 2(5) - 5\\v(5) = 12 - 10 - 5\\v(5) = -3$
