Step-by-step explanation:
Answer:
The value after 0 years = $ 800
The value after 1 year = $600
The value after 2 years = $450
The value after 3 years = $337.5
The value after n years = computer cost at (n-1) year -
Step-by-step explanation:
- he cost of computer = $ 800
- It losed 1/4th of value every year.
- The value of computer after 0 years = cost of computer = $ 800
- The value after 1 year = 800 - ( ) = $600
- The value after 2 years = 600 - ( ) = $450
- The value after 3 years = 450 - ( ) = $337.5
- The value after n years = computer cost at (n-1) year -
Answer:
its asking you what the slope of the line is (rise/run) and for the point at which the line crosses the y axis (verticle line)
Step-by-step explanation:
When finding the slope you count the number of units up and the number of units across. This would be -1/1 or -1 because the graph shows a scale of 100, and the slope is going down 100, and across 100. this makes the slope negative since it's going downwards. so the slope would be -100/100 which would simplify to -1.
the y-intercept is where the line crosses the y axis. if this point is below the x-axis, then the y-intercept would be negative. in this problem however, the line crosses the y-axis at the origin (0,0)
so your equation would be y=1x+0, but simplified it would be y=x (the one isnt used because there is a single x value and the +0 is gone because it holds no value)
Answer:
around 78 students since it isn't an even number
Step-by-step explanation:
You figure this out by doing:
155 times .50 or 50% = 77.5 and since you can't have half a person we'll round down, making it 77
Then you minus 77 from 155 = 78
