Answer:
Insert equation into desmos (free online graphing calculator)
the two x intercepts are -0.33333 and 1.5
1.83333 is the answer
The equation for this would be 2x+15000=102,000
2x=87000
x=43500
julian makes 58500
and tutor makes 43500
Answer:
really hard
Step-by-step explanation:
ask sheldon
Create 2 eq’n, let V = vans and B= buses
1. 150 = 8v + 14b
2. b + v = 15
isolate one variable and substitute it in to an equation:
b = 15 - v
sub “b” into first equation above:
150 = 8v + 14 ( 15 - v)
150 = 8v + 210 - 14v
-60 = -6v
10 = v
sub “v” into equation 2
b = 15 - v
b = 15 - (10)
b= 5
there will be 5 buses and 10 vans to hold 150 students.
