Question

I need help! Really bad a math.​

Answer 1

Answer:

12

Step-by-step 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

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

$\\ \sf\longmapsto 15+\dfrac{-18}{6}$

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

$\\ \sf\longmapsto 15-3$

$\\ \sf\longmapsto 12$
