To find the unit rate, divide total miles by number of gallons:
418 miles / 16 gallons = 26.125 miles per gallon
Round the answer as needed.
F(x) = 3x² + 6x - 1
The graph is a parabola open upward (a= 3>0) with a minimum.
Calculate the vertex:
x = -b/2a → x = -6/(2.3) = -1. Then the axis of symmetry is x = - 1
Now to calculate the minimum, plugin the value of x:
y = 3x² + 6x - 1
y = 3(-1)² + 6(-1) -1
y= 3 - 6 -1 and y = - 4,
Ten the vertex (minimum) is at (-1,- 4)
Answer:
4 hours it will take for them to be equal.
Step-by-step explanation:
every hour Umpt collects 4
every hour Yoy loses 1,
54 + 4 = 58 +4 = 62 + 4 = 66 + 4 = 70
74 - 1 = 73 - 1 = 72 - 1 = 71 - 1 = 70
