The left sum would be f0+f1+f2+f3
The right sum would be f1+f2+f3+f4
The trapezoidal rule value is:
(f0+f1)/2 + (f1+f2)/2+(f2+f3)/2 +(f3+f4)/2
This would put the trapezoidal rule in the middle , which makes the answer:
Lower sum < Trapezoidal rule Value < Upper sum
8:15 is the answer assuming the clock is at PM.
Multiply both sides by 2 to clear the fraction.
-3x + 6 <= 24
subtract 6 from both sides.
-3 x <= 18
divide both sides by -3, since you're dividing an inequality by a negative number you have to change the direction of the inequality sign.
x >= -6
5/1 is the reciprocal of 1/5
Peter pays a membership of 45 and he pays $ 6 per movie
Jacob : y = 5x + 25.....this is basically saying that Jacob pays a membership of $ 25 and he pays $ 5 per movie
so Peter pays (45 - 25) = 20 dollars more for the membership
