Answer:
-1.25.
Step-by-step explanation:
Given : [tex]-4x-1 = 5^x+4[/tex]
To Find: Solve the equation for x by graphing
Solution:
[tex]y=-4x-1[/tex]
[tex]y= 5^x+4[/tex]
Plot the graphs
The intersection point of these two equations will give the value of x.
So, [tex]y=-4x-1[/tex] -- green line
[tex]y= 5^x+4[/tex] -- purple line
Intersection point : (-1.282,4.127)
So, x = - 1.282 ≈ -1.25
The value of x is -1.25.
