Answer:
-60x+20 = -400
x equals 7
Step-by-step explanation:
Answer: There are no real solutions
Answer: 7%
300t = 350(t-1)
300t = 350t-350
-50t=-350
t = -350 /-50
t = 7 hours
y = -1/3x + 5
-1/3 is the slope because the line goes down 1 unit and right 3 units.
The y-intercept is 5 because that is where the line crosses the y-axis.
