Heya!
Answer is 
<u>EXPLANATION</u><u> </u><u>:</u><u>-</u>
Given
x-y= -5
x-y=1³
Substitute value of x - y as 1³ in first equation,
=> x-y= -5
=> 1³ = -5
As we can't do anything more to solve, we can finally write as :

Well since you have duble the recipe then its=s:
8/2=4/2=2/2=1
well it's 1!
A) Y1-Y2/X1-X2
9-4/8-(-2) = 5/10= 1/2
b) 1/2x+b=y <-- plug in a point
1/2(-2)+b=4 <--plugged in (-2,4)
-1+b=4 <-- simplify/solve
b=5
c) 1/2x+5=y
A=2πrh+2πr2
the surface area of a cylinder
You would multiply 29.50 x 0.07 which would give you 2.065. The tax amount would be $2.07. The total after tax would be $31.57.
