Find slope
slope betwen 2 points (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
so
first make denoms same
denom is 10
(4/5,1/5) turns to (8/10,2/10)
(1/2,3/2) turns to (5/10,15/10)
slope=(15/10-2/10)/(5/10-8/10)=(13/10)/(-3/10)=13/-3=-13/3
use point slope
use (4/5,1/5)
y-y1=m(x-x1)
a point is (x1,y1) and slope is m
y-1/5=-13/3(x-4/5)
expand
wait, we don't need to do that, the only one with slope -13/3 is D
answer is D
Answer:
2x²y+(x²y-2xy²) = 3x²y-2xy²
(5xy²-x²y) +3x²y = 5xy²-2x²y
4x²y+(x²y+xy²) = 5x²y+xy²
x²y+(-2xy²-4x²y) = -3x²y-2xy²

Answer:
Altogether they sell <u>1634</u> apples.
Step-by-step explanation:
GIven:
Bob, Joe and Larry sold apples at the farmers market.
<u><em>Bob sold 86 apples. </em></u>
<u><em>Joe sold 12 times as many as Bob. </em></u>
<u><em>Larry sold half as many apples as Joe. </em></u>
Now, to find the total apples Bob, Joe and Larry they all sell together.
<u>Number of apples Bob sold</u> = 86.
<u>Number of apples Joe sold</u> = 12 times of 86.

<u>Number of apples Larry sold</u> = 


Now, to get the apples they sell altogether we add the number of apples sold by Bob, by Joe and by Larry:


Therefore, altogether they sell 1634 apples.
Answer:
8.75+7.45=16.2. 16.2 is equal to $16.20 so 48.00-16.20=31.8. Jonathan had $31.80 left.
