Answer:
tally mark also called hash marks and they are a unary numeral system
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
This is the equation of the line
To graph a line we need two points
<em>Find the intercepts</em>
1) The y-intercept is the value of y when the value of x is equal to zero
For x=0
The y-intercept is the point (0,3)
2) The x-intercept is the value of x when the value of y is equal to zero
For y=0
The x-intercept is the point (-1.5,0)
To draw the graph of the line plot the intercepts and join the points
using a graphing tool
see the attached figure
74 cause an absolute value of any number will always be positive.

The distance travelled by the train with constant speed of r miles will be 3r.
<h3><u>
What is Speed?</u></h3>
- The most crucial scientific notion is measurement. Base or physical fundamental units are used to quantify a wide range of quantifiable quantities.
- One such measurable metric is speed, which calculates the ratio between the distance an object travels and the time needed to cover that distance. Let's explore speed in-depth in this session.
- The pace at which an object's location changes in any direction. When an object travels the same distance in the same amount of time, it is said to be moving at a uniform speed.
- When an object travels a different distance at regular intervals, it is said to have variable speed.
We know the formula of distance linking the speed and the time.
Distance = speed × time
Substituting the given values to get:
Distance = r × 3
Distance = 3r
