Step-by-step explanation
5^x-4=7
reserve 4
log sides
x-4 log5 and log7
x-4=log7/log5
+4 or number of your equation
x=log5/log7 +4
use calculator
get answer
5.209

To find the intercepts, we can set the opposite variable equal to 0 and solve.
Let's find the x intercept first.
5x - 4(0) = -20
5x = -20
Divide both sides by 5.
x = -4
<h3>The x intercept is -4.</h3>
Now let's find the y intercept.
5(0) - 4y = -20
-4y = -20
Divide both sides by -4.
y = 5
<h3>The y intercept is 5.</h3>
