Answer:

Option D. x=-2.5

Step-by-step explanation:

we have

[tex]-2x-3=3^x+2[/tex]

I can divide the expression above in a system of two equations

[tex]y=-2x-3[/tex] ----> equation A

[tex]y=3^x+2[/tex] ----> equation B

Solve by graphing

The solution is equal to the x-coordinate of the intersection point both graphs

using a graphing tool

The intersection point is ( -2.5,2.1)

see the attached figure

therefore

The solution is x=-2.5
