Easy,
23y-(7x-2y)+x
<span>There is an imaginary</span> 1 in front of the parentheses, making it,
23y-1(7x-2y)+x
Now, distribute the 1.
-1*7x= -7x
and
-1*-2y= 2y
Leaving your problem looking like...
23y-7x+2y+x
Combine your apples and oranges.....
25y-6x
Thus, your answer.
Nope. its y=3x-1. the y intercept is -1, so we put that at the end. And if we take 2 points on the line and use y/x, we get 3/1 or 3, and this is our slope. Also the line is going up so its not negative
Answer:
y cannot be -9
Step-by-step explanation:
The other word is discontinuity
It is what y cannot be
The denominator cannot be zero so
y+9 cannot be zero
y cannot be -9
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:
8 unit ^2 or 8cm^2
Step-by-step explanation:
area 1
1/2 ( 3 x 3 ) = 4.5 unit ^2
area 2 we split the triangle into half
= 1/2 ( 2 x 2) = 2 unit ^2
we know the other half is also 2 unit ^2 but we add then subtract
1/2 (1 x 1) = 0.5^2
To get
4.5 + 2+ 2 - ( 0.5) = 8 unit ^2
