Answer:
P=3T-50
Step-by-step explanation:
Form the given four values we can assume a linear relationship between profit and the no of tickets sold.
Let the equation corresponding to that be some P=aT+b.
Now substitute the first set of values(100,50) in the above equation we get
100=50a+b.
Now substituting second set of values (100,250) we get 250=100a+b.
Let these equations be eq1 and eq2.
Now substract eq1 from eq2 we get 50a=150 or a=3.
Substitite value of a in one of the equations we get b=-50.
∴P=3T-50
Answer:
There is 9 total combinations.
Step-by-step explanation:
Tbh i only know problem 14.
The x-intercept is on the x-axis.
In coordinate points (x,y).
The two x-intercepts are (-1,0) and (2,0).
To find the x intercept using the equation of the line, plug in 0 for the y variable and solve for x. You can also use the graph of the line to find the x intercept. Just look on the graph for the point where the line crosses the x-axis, which is the horizontal axis. That point is the x intercept.
