S = (10 x1 /2) + (1/2x- 2x 1/2²)
5 + (-0.25)
= 4.75
Answer:
I would help you
Step-by-step explanation:
But I'm really lazy and I really don't like math. I'm not good at it and I think I failed it last semester. true story bro.
(5,22.45),(7,25.45)
slope = (25.45 - 22.45) / (7 - 5) = 3/2 or 1.5
y = mx + b
slope(m) = 1.5
use either of ur points...(5,22.45)...x = 5 and y = 22.45
now sub and find b
22.45 = 1.5(5) + b
22.45 = 7.5 + b
22.45 - 7.5 = b
14.95 = b
so ur equation is : y = 1.5x + 14.95.......this means that each quart of oil costs $ 1.50 and the labor fee costs $ 14.95
10 cars in each row
5 cars x 6 rows = 30
30 divided by 3 = 10 cars in each row
