Answer:
y ≥ 6.25
Step-by-step explanation:
f(x)=4x²+2x-6
positive (4) leading coefficient, curve is left up and right up
x coordinate of vertex: x = - b/2a = - 2/2*4 = - 1/4 (-0.25)
y = 4*(-1/4)² + 2*(-1/4) - 6 = -6 1/4 (-6.25) ... extreme
range: y ≥ - 6.25 [-6.25,∞)
Answer:
0.03333333333 = 33/1000 = 3.3%
Step-by-step explanation:
Total $= $123
Flat fee= $55
Daily cost= $8.50
d= number of days rented
Total cost equals (the daily cost times the number of days rented) plus the flat fee.
T= (Daily cost)(# Days) + Flat fee
$123= $8.50d + $55
ANSWER: $123= $8.50d + $55
