Answer:

  • 16

Step-by-step explanation:

<u>Given:</u>

  • f(x) =3x - 8 and g(x) = x² + 4
  • f(g(- 2)) = ?

<u>First find g(- 2):</u>

  • g(- 2) = (-2)² + 4 = 4 + 4 = 8

<u>Find f(8):</u>

  • f(8) = 3*8 - 8 = 24 - 8 = 16

g(-2):-

\\ \sf\longmapsto (-2)^2+4

\\ \sf\longmapsto 4+4

\\ \sf\longmapsto 8

Now

\\ \sf\longmapsto f(x)=3x-8

\\ \sf\longmapsto f(g(-2))=f(8)

\\ \sf\longmapsto 3(8)-8

\\ \sf\longmapsto 24-8

\\ \sf\longmapsto 16

14 = 2y/5 what is the solution?
Gnom [1K]

Answer:

y=35

Step-by-step explanation:

y in (-oo:+oo)

14 = (2*y)/5 // - (2*y)/5

14-((2*y)/5) = 0

(-2/5)*y+14 = 0

14-2/5*y = 0 // - 14

-2/5*y = -14 // : -2/5

y = -14/(-2/5)

y = 35

y = 35
