Answer:
It is Commutative
Step-by-step explanation:
An operation ∆ is said to be Commutative if a∆b=b∆a ∀ a,b ∈ ℝ.
Given the operation ∆ defined by:
a∆b=a X b

a∆b=
=3
Similarly, for the right hand side.

Therefore:
b∆a=
=3
These are the two ways of solving this problem and we have in fact shown that the operation is commutative as:
a∆b=b∆a=3
Answer:
V = 512 cm³
Step-by-step explanation:
Use the formula V = s³ to find the volume of the cube
V = 8³
V = 512 cm³
Do you mean 3/√11 ? In this case, you'll have to multiply both, numerator and denominator by the denominator ...

Any line can be graphed using two points. Select two x
values, and plug them into the equation to find the corresponding y
values.

Graph the line using the slope and the y-intercept, or the points.
Slope: 5
y-intercept: (0,−4)

6) check picture
a) all three lines are parellel and have the same slope. the only difference is that they are translated on different points on the x-axis.
not sure about the rest sorry :(
