Both climbers rested on the wall at a constant height for 2 minutes.

<h3>How to determine the true statement?</h3>

The illustrative graph that represents the climbers' movement is added as an attachment

From the attached graph, we have the following observation

  • The line of Abby's movement is horizontal from x = 4 to x = 6
  • The line of Brynn's movement is horizontal from x = 5 to x = 7

The difference between the endpoints of both horizontal line is

Difference = 6- 4 = 2

Difference = 7 - 5 = 2

This means that both Brynn and Abby stopped for 2 minutes

Hence, the true statement about is that (d) Both climbers rested on the wall at a constant height for 2 minutes.

One electrician charges his customers a $60 service fee plus $35 per hour.
gavmur [86]

Answer:

2 hours; $130

Step-by-step explanation:

We can do this by setting up an equality since we are finding when they are the same. Say x is the number of horus:

65 * x = 60 + 35* x

30 * x = 60

x = 2 hours

The cost will be the same at two hours, and plugging it in, we can get 65*2=130.
