Answer:
The required inequality is:
Step-by-step explanation:
Consider the provided information.
Gurnaz has been mowing lawns to save money for a concert. Gurnaz will need to work for at least six hours to save enough money, but he must work fewer than 16 hours this week.
Let the number of hours Gurnaz work is represented by x.
Gurnaz will need to work for at least six hours to save enough money,
That means he can work 6 or more than 6 hours,
He must work fewer than 16 hours this week. That means the value of x should be less than 16.
Thus, the required inequality is:
Now draw the graph of the inequality.
Use a dot or close circle to represents ≤ or ≥ and use a open circle to represent < or >.
The value of x is greater than or equal to 6 also the value of x is less than 16. The required graph is shown below.
Answer:
5.5
Step-by-step explanation:
The y-intercept of the line graph shown above is the value of the point where the line cuts the y-axis. The y-intercept of this graph is between 5 and 6. However, we can get an accurate value by calculation. This can be done by generating an equation of the line.
Recall the slope-intercept equation, , where m = slope of the line, b = y-intercept.
To generate the equation of the line, first find slope using the points (-2, 7) and (6, 1):
.
Substitute m = ¾ and the coordinates (6, 1) into the slope-intercept equation to find the y-intercept (b):
Therefore, b = y-intercept = 5.5.
To generate the equation of the line, plug in the values of m and b, we would have:
y = ¾x + 5.5
The y-intercept of the line of the graph is 5.5.
