Step-by-step explanation:
Gradient is just another similar term for slope l, 
, and it can be calculated by 
where 
and 1
is the 
-coordinates of point 
We let 
be point 
and 
be point 
, we can then write the equation:
.
It also says that the points are with a gradient of so 
. We can then write the equation:

Answer:
they drink 1.667 gallons a week. it takes about 6.5 days to drink a whole gallon
Step-by-step explanation:
take 10/6 to get 1.667 then how many days would it take to drink 1 whole gallon
-3y-8x+3x^2 is the simplified version of 7y+2x-10y+3x^2-10x
4.) 2(x-1)+3= 2x+1
Distribute the 2, multiply the 2 by x and -1.
2*x= 2x (all you need to do is put 2 in front of x)
2*-1= -2
2x-2+3= 2x+1
Combine like terms.
2x+1=2x+1
Subtract one on both sides.
2x=2x
Divide by 2 into both sides.
x=1
We can check this by plugging it in.
2(1-1)+3= 2(1)+1
2(0)+3= 2+1
0+3=3
3=3 <== this works
I hope this helps!
