Answer:
a) 580 - 16n
b) 9850 - 271.72n
Step-by-step explanation:
a) starting number of bales = 580
each day, the farmer feeds out 2 bales of hay to each yard. he has 8 yards, so he feeds out 2 bales 8 times for a total of 2 * 8 = 16 bales. Therefore, he loses 16 bales each day
After the first day, he has 580-16 = 564 bales. After the second, he has 564-16 = 548 bales, and so on. He loses 16 bales n times for n days, and as a result, his final amount of bales is
original amount - amount lost = 580 - 16n
b)
First, we can calculate how much a bale weighs.
average = sum/count = 9850 kg / 580 ≈ 17 kg
Therefore, as he loses 16 bales of hay, he loses 17 kg 16 times, or approximately 271.72 kg of hay every day. For n days, he loses 271.72n kg. This brings his final amount to be
starting - amount lost = 9850 - 271.72n
Answer:
(-1, -2)
Step-by-step explanation:
when x = -1 and y = -2,
(-2 · -1) - (-2) = 2 + 2 = 4
Answer:
Slope = -4 y-intercept= -8
Step-by-step explanation:
This equation is in slope intercept form, which is always written in the format of y=mx+b. The m means slope and the b means y-intercept, so you can just substitute the variables for the values.
SOLUTION
In this question, we are meant to expand the expression:
I believe that it would be 13, unless you were trying to make the 9 negative. Hope that helps.
