Question

What is the answer for this math?​

Answer 1

Answer:

x=-4.992 and x=-0.434

Step-by-step explanation:

we have    

$\frac{\sqrt{3x+15}}{5}=2^{x}$

we can divide the equation above into two equations

so

$y=\frac{\sqrt{3x+15}}{5}$ ----> equation A

$y=2^{x}$ ----> equation B

Solve by graphing

The solutions of the system are the x-coordinates of the intersection points both graphs

using a graphing tool

The solutions are x=-4.992 and x=-0.434
