1. The ordered pair (-1, -1) is a solution of the system -4x + 2y = 2 and x + y = -2.

Nastasia [14]

1: (-1,-1) is (x, y) to see if it is a solution, you would just plug in x and y and see if the equation is true.
-4 (-1) + 2(-1) = 2
4 + -2 = 2
2 = 2 CORRECT
So... plug in x and y in the second equation to Make sure it works for that one too.
-1 + -1 = -2
-2 = -2 CORRECT
So, yes. (-1,-1) is a solution to both equations.

Which expression is equivalent to (5x^3)(2x)^3

Elanso [62]

Answer:

$\large\boxed{(5x^3)(2x)^3=40x^6}$

Step-by-step explanation:

$(5x^3)(2x)^3\qquad\text{use}\ (ab)^n=a^nb^n\\\\(5x^3)(2^3x^3)=(5x^3)(8x^3)\qquad\text{use commutative law}\\\\=(5\cdot8)(x^3x^3)\qquad\text{use}\ a^na^m=a^{n+m}\\\\=40x^{3+3}=40x^6$
