Part A)
y < 2*x
y > 4/5*x
The graph will shade below the line y = 2x (not including the line),
and above the line y = 4/5*x (not including the line).
Where the shaded regions overlap is the solution area.
In the graph, the overlapping region is darkest.
part b) verify that point C and point F satisfy the inequalities
plug in point C and point F separately.
you should get a true statement, each time
part c) if we graph
y < -2x + 2
over the plotted points
lets see what points it covers
The shade region covers points A,B,D
so those are the schools she can attend
Answer:
The third graph is the correct one.
Step-by-step explanation:
D. Is the one which has slope -3
It is because the point of it’s slopes are
( 0,0) and (1,-3)
So the slope will be
(Y2 - Y1)/(X2-X1)
Hence -3 is the slope of graph D.
Answer:
10 years until the value of the car is 11000 dollars
Step-by-step explanation:
The value of the car after t years is modeled by the following equation:
In which V(0) is the initial value and r is the yearly depreciation ratio, as a decimal.
A new car is purchased for 21100 dollars.
This means that
The value of the car depreciates at 6% per year.
This means that . So
To the nearest year, how long will it be until the value of the car is 11000 dollars?
This is t when
To the nearest year
10 years until the value of the car is 11000 dollars
