Answer:
y=640-3x
Step-by-step explanation:
The total amount of ounces in the bucket is 640, and it decreases by 3 each minute. For example, if you plug in 3 for x into that equation (which would represent 3 minutes), you would lose 9 ounces of water, which makes sense in the terms of the equation.
Count the difference of the x values between the two points (the run of the slope) and the difference of the y values between the two points (the rise of the slope). That would get you the rate of change, or slope, of the line.
Answer:
1. 201.06
2. 78.54
Step-by-step explanation:
A

π
r
22/7× 8²=201.06
22/7× 5²=78.54
Step-by-step explanation:
Consider x⅓ =a
then the following expression can be written as
a²+a-2
a²+2a-a-2
a(a+2)-1(a+2)
(a+2)(a-1)
a= -2 or, a= 1
Putting the value of a
x⅓ = -2 and, x⅓ =1
