First of all, recall that division by zero is undefined; it's nonsensical; it's just not allowed.So zero certainly needs to be excluded when dividing.
But what about multiplying by zero?
The problem is that multiplying by zero can change the truth of an equation:
It can take a false equation to a true equation.
To see this, consider the false equation ‘
2 = 3
Multiplying both sides by zero results in the new equation
2 ⋅ 0 = 3 ⋅0 (that is, ‘0 = 0’), which is true.
y = (9x) ^ (1/3)
exchange x and y then solve for y
x = (9y) ^ (1/3)
cube each side
x^3 = 9y
divide each side by 9
1/9 x^3 = y
the inverse function is 1/9 x^3
Answer:
4/15
Step-by-step explanation:
You would do it as follows
I-8/15I reduce the fraction by 2
I-4/25I the absolute fraction is always positive
So the solution is
4/25
Alternative forms are:
0.16 or (2/5)^2 (Just incase)
d
The rule (x, y ) → (x + 4, y - 6 )
means add 4 to the original x- coordinate and subtract 6 from the original y- coordinate, thus
P(- 8, 3 ) → P'(- 8 + 4, 3 - 6 ) → P'(- 4, - 3 )
Q(- 8, 6 ) → Q'(- 8 + 4, 6 - 6 ) → Q'(- 4, 0 )
R(- 3, 6 ) → R'(- 3 + 4, 6 - 6 ) → R'(1, 0 )
