The system has one solution because the slopes are different. TO solve...
5x - 6y = -25
4x - 3y = -20, multiply this equation by -2
5x - 6y = -25
-8x + 6y = 40, now use combination to get
-3x = 15, so x = -5. Now plug this back into either original equation to get
5*(-5) - 6y = -25
-6y = 0, so y = 0, so the solution is (-5,0)

Answer: 30×2n=C
Step-by-step explanation:
30$ is flat fee so no variable
2$ dollars per person so "n" (the number of people) is times 2
= the final cost (C)
Answer:
0 < x < 2.5
Step-by-step explanation:
-16x² + 38x + 5 = 0
-16x² + 40x - 2x + 5 = 0
-8x(2x-5) - 1(2x-5) = 0
x = -⅛ , 2.5
0 < x < 2.5
