Answer:
is represented in the graph.
Step-by-step explanation:
To find the linear inequality for the shown graph.
Steps:
Finding the equation of dotted line shown in the graph.
Equation of line is given by
where is slope of line and
is y-intercept.
Given points:
Slope of the line
∴
From the given points we can see that point of y-intercept is given i.e. the point where the line intersects the y-axis
∴
So equation of line:
Since the shaded area in the graph is above the line and the line is dotted this means that is greater than the equation of line.
So, the inequality can be given as:
Given:
The table of values.
Hours (h) Dollars (d)
1 42
2 84
3 126
4 168
5 ?
To find:
The correct statements about the table.
Solution:
From the given table it is clear that,
This pattern can be defined as
Multiply h by 42 to get d. So, option A is correct.
Using this pattern, we get
The missing value in the last row is 210. So, option D is correct.
From the given table it is clear that the rate of change is $42 per hour because dollar is increasing by 42 in every hour.
A real-world situation that is represented in the table is “Richard is a video game designer and earns $42 per hour.”
Therefore, the option E is correct.
