Answer:
X+ 7 = 21 - 7 - 7x = 14
Step-by-step explanation:
replace x values and y values with the answer choices.
since the coordinate pair it is safe to assume that d will be the correct answer.
use the graph to confirm that the solution is (1,0)
the blue line intersects at (1,0), so the solution for the system of equations is (1,0)

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
