(c) 20 ; each mile takes 8 minutes, therefore if you divided 160 by 8 your product would be 20
Would appreciate your sharing actual inequalities to graph. Otherwise the topic is a bit broad.
Supposing you wanted to graph the inequality x<5:
Draw a dashed line through x=5, and then shade the area to the left of this line.
Supposing you wanted to graph the inequality x less than or equal to 5:
Draw a solid line through x=5, and then shade the area to the left of this line.
Please, respond with an inequality that you want to graph, and I'll help you with it.
Vertex is -b/2a. The variable b=2 and a=2. That finds the x coordinate of the vertex. Then to find the y coordinate you just plug the number you got for x (-1/2) into the equation. Like so:
y = 2x+2
y = 2(-1/2)+2
y = -1+2
y = 1
So your vertex is ( -1/2, 1 )
To graph your vertex you take your x coordinate (-1/2) and find it on the x axis of the graph (horizontal line). Then do the same for y (1) (on the vertical axis.
Now that you have your vertex graphed you can find out if it is minimum or maximum by looking at the direction in which the slope is going. If it goes in the positive direction (up) then it is a minimum since that is the lowest point that the line touches. If it is maximum it is opposite. The line faces down and the highest point the line touches is that point.
Answer:
False.
Step-by-step explanation:
If we substitute a for 6, the inequality would become 6 > 6. That is not true because 6 cannot be greater than itself.
