Answer:
12 hours
Step-by-step explanation:
Step one:
given data
base fee= $60
charge per hour= $15
let the number of hours the plumber work be x
the linear function for the charge is the equation of line.
that is y=mx+c
Step two:
given that y=$240
240=15x+60
240-60=15x
180=15x
divide both sides by 15 we have
x=180/15
x=12
<u>The number of hours is 12</u>

Answer:
one
Step-by-step explanation:
they meet at only one point, thus their system of equations has as solution only those coordinates.
Answer:
C) 8
Step-by-step explanation:
Consecutive angles are equal to 180. So 22x+4+180. Solve that to get x=8. Hope I helped and post more questions :)
The given process is an example of a cluster system.
<h3>What is the cluster system?</h3>
The clustered systems are a combination of hardware clusters and software clusters.
The hardware clusters help in sharing of high-performance disks between the systems.
The software clusters makes all the systems work together.
Each node in the clustered systems contains the cluster software.
A cluster refers to a group of inter-connected computers where it works together to support applications and middleware (e.g. databases).
In a cluster, each & every computer is known to be a “node”.
