The answer is $320.
In order to solve this, you can start off by turning this word problem into an expression.
$70x → $70 per hour (x represents the amount of hours)
+40 → plus $40 for the call
Substitute the x for 4 and solve the equation.
70x+40
70(4)+40
280+40
320
The plumber charges $320 for 4 hours of work.
Answer:
Option d) all real numbers
Step-by-step explanation:
we have
![y=\log8^x](https://tex.z-dn.net/?f=y%3D%5Clog8%5Ex)
using a graphing tool
The graph of the equation is a line that represent a direct variation ( the line passes through the origin)
therefore
The domain is all real numbers ---->interval (-∞,∞)
The range is all real numbers ---->interval (-∞,∞)
