Step-by-step explanation:
(x+2y)(x-2y)
- x^2-2xy+2xy-(2y)^2
- x^2-4y^2
Slope= y^2-y^1
————
x^2-x^1
slope= 12-0
——-
6+2
slope= 12
—-
8
slope= 3/2
perpendicular slope is the opposite reciprocal
perpendicular slope= -2/3
I=prt
20=p X .05 X 5
20 = p X .25
20/.25 = p
80 = p
She started with $80
Answer:
Not Linear
Step-by-step explanation:
A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 3.
Less by far because 3.5 cups would be less than half
