Question

I need help! Really bad a math.​

Answer 1

12

Explanation:

Substitute -18 into the equation

h(-18) = 15 +(-18)/6

h(-18)= 15 + (-2)

h(-18)= 15-2

h(18)=12

12 is the final answer

Answer 2

`\\ \sf\longmapsto h(-18)`

`\\ \sf\longmapsto 15+(-18)/(6)`

`\\ \sf\longmapsto 15+(-3)`

`\\ \sf\longmapsto 15-3`

`\\ \sf\longmapsto 12`
