Answer:

s b. x = 7/4.

Explanation:

To graph the equation 5^(-x) + 7 = 2x + 4, we need to plot the left-hand side (LHS) and right-hand side (RHS) of the equation and find the point of intersection.

Plot the LHS: LHS = 5^(-x) + 7

Plot the RHS: RHS = 2x + 4

We'll look for the point where these two curves intersect, which will be a solution to the equation. Let's plot the graph:

Here's a graph of the equation:

LHS = 5^(-x) + 7 (represented by a curve)

RHS = 2x + 4 (represented by a straight line)

Now, let's identify the point of intersection on the graph:

Based on the graph, it appears that the curves intersect at approximately x = 7/4.
