Answer:
In the sciences, many times it is necessary to be able to interpret graphs as well as be able to graph certain equations. Often data is available in a graphical format and you must be able to extract the necessary information. Other times, it may be helpful to plot an equation in order to fully understand a problem. However, graphing can be difficult for some students. The format in this section is a little different. The first part will be simply showing what some special equations look like in graphical form and the second part will be a series of questions to help you understand graphs better.
Step-by-step explanation:
It's 6.9. Just do the circumference divided by pi
Answer:
Step-by-step explanation:
3x +1 = 2x +7 subtract 1 from both sides ( first)
3x +1 -1 = 2x + 7 -1
3x = 2x + 6 subtract 2x brom both sides (second)
3x -2x = 2x -2x +6
5x = 6
Answer:
-2
Step-by-step explanation:
We usually start measuring the height from the ground, so basically the positive direction is above the ground, for example 2 is the best number which represents 2m above the ground.
So the negative sign represents the depth below the ground.
