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.
