Answer:

C. 7

Step-by-step explanation:

First you have to find the unit rate of this equation

The unit rate is 20 students for every 1 teacher because 40 divided by 2 is 20

so if you do 140 divided by 20 your answer is 7

there are 7 teachers

How can I tell if a system of equations has one, no, or infinitely many solutions?
Fittoniya [83]

Answer:

There are many ways to interpret if whether or not a system of equations has solutions or not. Here is one way that is most ideal for most, if not, all equations: using graphs.

  • If the graphs of the set of equations do NOT intersect, then there are no solutions (because no x or y value will ever make both equations true)
  • If the graphs of the set of equations DO intersect at one point, then ONLY that one point will make both equations true. (One solution)
  • If the graphs of the set of equations are identical on the graph, then there are infinite solutions that make both equations true.

Find the distance between these points. C(0, 4), T(-6, -3) √(37) √(109) √(85)
finlep [7]

Answer:

The answer is

<h2>\sqrt{85}</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

<h3>d =  \sqrt{( {x1 - x2})^{2}  +  ({y1 - y2})^{2} }  \\</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

C(0, 4), T(-6, -3)

The distance between them is

<h3>|CT|  =  \sqrt{ ({0 + 6})^{2}  +  ({4 + 3})^{2} }  \\  =  \sqrt{ {6}^{2} +  {7}^{2}  }  \\  =  \sqrt{36 + 49}</h3>

We have the final answer as

<h3>\sqrt{85}</h3>

Hope this helps you
