Answer:
The required inequality is:
The graph is shown in figure.
Step-by-step explanation:
Consider the provided information.
Chad will need at least 24 minutes to complete the 5K race. However, he wants to finish in under 30 minutes.
Let the time taken to finish the race is represented by x.
Chad need at least 24 minutes and he wants to finish in under 30 minutes.
Thus, the required inequality is:
Now draw the graph of the inequality.
Use a dot or close circle to represents ≤ and use an open circle to represent <.
The value of x is greater than or equal to 24 but less than 30, Thus the required graph is shown in figure.
Answer: Line joining ordered pairs (0, 10) and (15, 0) and Shade the portion of the graph below this line which lies within the first quadrant.
Step-by-step explanation:
Here, The club charges $y an hour for each child and $x an hour for each adult.
And, according to the question,
In the family 3 children and 2 adults visited a health club such that the family does not want to spend more than $30 an hour at the health club.
That is,
Which is the required inequality.
Since at origin, (true)
That is, the inequality must contains the origin.
Therefore, shaded region will occur below the line.
Also, x-intercept of the given line is (15,0)
And, y-intercept of the given line is (0,10)
Thus the line will join the order pairs (15,0) and (0,10)
Also, and
( because charges can not be negative)
Therefore the shaded region will only contain the first quadrant.
