To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -8 ± √((8)^2 - 4(3)(2)) ] / ( 2(3) )
x = [-8 ± √(64 - (24) ) ] / ( 6 )
x = [-8 ± √(40) ] / ( 6)
x = [-8 ± 2*sqrt(10) ] / ( 6 )
x = -4/3 ± sqrt(10)/3
The answers are -4/3 + sqrt(10)/3 and -4/3 - sqrt(10)/3.
Answer:
2 small; 3 large
Step-by-step explanation:
Using s and L for the number of small and large cars, respectively, we have ...
5s +8L = 34 . . . . number of passengers
s + L = 5 . . . . . . . number of cars
5s +8(5 -s) = 34 . . . . substitute for L
-3s +40 = 34
-3s = -6 . . . . . . subtract 40
s = 2 . . . . . . . . divide by -2
L = 5-2 = 3
2 small cars and 3 large cars were rented.
