Question

S(x)= -3(x-2/3) + 19; s(x) = 0

Answer 1

x = 7

Explanation:

Given s(x) = - 3(x -
`(2)/(3)`) + 19 and s(x) = 0, then equate the right sides, that is

- 3(x -
`(2)/(3)` ) + 19 = 0 ( add 19 to both sides )

- 3(x -
`(2)/(3)` ) = - 19 ← distribute the parenthesis

- 3x + 2 = - 19 ( subtract 2 from both sides )

- 3x = - 21 ( divide both sides by - 3 )

x = 7
