Question

Solve the equation for x by graphing

Answer 1

Graph each side of the equation and the solution is what the x-value is at the point of intersection. In this case is about -1.25.

Answer 2

Answer:

-1.25.

Step-by-step explanation:

Given : $-4x-1 = 5^x+4$

To Find: Solve the equation for x by graphing

Solution:

$y=-4x-1$

$y= 5^x+4$

Plot the graphs

The intersection point of these two equations will give the value of x.

So, $y=-4x-1$  -- green line

$y= 5^x+4$   -- purple line

Intersection point : (-1.282,4.127)

So, x = - 1.282 ≈ -1.25

The value of x is -1.25.
