What is the value of h(g(1.5))h(g(1.5))h, left parenthesis, g, left parenthesis, 1, point, 5, right parenthesis, right parenthesis?

Respuesta :

the question is Let h(x)=2x+5  and g(x)=8-3x
what is the value of 
h(g(1.5))
 the answer 

h(g(1.5))= 2g(1.5)+5, and g(1.5)=8-3(1.5)=3.5, so
h(g(1.5))= 2(3.5)+5= 12
h(g(1.5))= 12
