Aplumber charges a $75 flat fee for jobs lasting up to an hour and $30 for each hour of labor after the first hour. Which
tamaranim1 [39]
<h3><u>Answer</u>:- </h3>

\longrightarrow \sf 75+ 30(h-1)

<h3><u>Solution:-</u></h3>

<u>Given </u><u>that </u><u>:</u><u>-</u>

  • job last for h hours
  • Cost of job lasting more than 1 hour = $30
  • Cost for the first hour = $75

\leadstoRemaining hours for which the job will last after first hour= (h-1)

<u>Therefore</u>,

Cost for subsequent hours = 30×(h-1)

= 30(h-1)

Total Cost for job = Cost for 1st hour + Cost for subsequent hours

\quad\quad\quad\quad\quad\quad\quad\quad\boxed{\sf{= 75+30(h-1)}}

Graph the solution of 2 ≥ 4 - v
Lerok [7]
For this case we have the following inequality:
 2 ≥ 4 - v
 The first thing we must do in this case is to clear the value of v.
 We have then:
 v ≥ 4 - 2
 v ≥ 2
 Therefore, the solution set is given by:

Does anyone know how to do this??
Fynjy0 [20]

Answer:

  y > 11/2

Step-by-step explanation:

This is solved the same way a 3-step equation is solved.

<u>Step 1</u>: subtract the smaller variable term from both sides.

  4y -2y +3 > 2y -2y +14

  2y +3 > 14

<u>Step 2</u>: subtract the constant with the variable term.

  2y +3 -3 > 14 -3

  2y > 11

<u>Step 3</u>: divide by the coefficient of the variable.

  2y/2 > 11/2

  y > 11/2

_____

<em>Additional comment</em>

By choosing to subtract the smaller variable term in the first step (regardless of which side of the inequality it is on), we ensure that the remaining variable coefficient is positive. That means we can do step 3 without worrying about changing the direction of the inequality symbol, because we're dividing by a positive number.
