The formula for a come is V=πr^2h/3.
The square in the graph represents one unit. In the diagram, the line has coordinates (0,4) and (4,0). Use the cpordinates, find the gradient and the equation using y = mx + c. So the equation of this line is x + y = 4. Now having obtained the equation of yhe line, the shaded part is below the line, therefore the inequality is : x + y =< 4
Answer:
X would be x < 9
Step-by-step explanation:
You would do this equation like any other equation, but with the equal sign being greater or less than. So you would add 4 on both sides to get x < 9
