Create a system of 2 equations
Let x be daily fee and y the mileage charge, then
4x + 370y = 244.50...........(1)
3x + 190y = 161.50..............(2)
If we multiply (1) by 3 and (2) by -4 and add the 2 equations we eliminate x:-
12x + 1110y = 733.50
-12x - 760y = -646 Adding :-
350y = 87.5 so y = 0.25
Plugging y = 0.25 into eqation (1) we get 4x = 244.50 - 0.25 * 370
giving x = 38
Answer is daily fee = $38 and mileage charge = $0.25 per mile.
The correct answer is: 27 .

Melody has $27.75 you just subtract 45.00 and 32.75 and get 12.25 then you add 15.50 and get 27.75

Answer:
hyperbola
Step-by-step explanation:
A graphing calculator shows the equation is that of a hyperbola.
__
Multiplying by the denominator gives ...
r(2 -3sin(x)) = 1
2r -3y = 1 . . . . . . . . substituting y=r·sin(x)
2r = 1 +3y . . . . . . . .isolating r
4r² = 1 +6y +9y² . . squaring both sides
4(x² +y²) = 1 +6y +9y² . . . . . substituting x²+y² = r²
4x² -5y² -6y -1 = 0 . . . . . . . . general form equation of a hyperbola
