Which of the following demonstrates the commutative property across multiplication for 2×10×7

1 answer:

4 0

Commutative property basically states that u can " commute " ...move the numbers around

so the commutative property of 2 * 10 * 7 could be 7 * 2 * 10... or 10 * 7 * 2...or 10 * 2 * 7 or 2 * 7 * 10....I think u get what I mean

Which of the following functions is graphed below.

Answer: Option A

$y=\left \{ {{x^2 +2;\ \ x$

Step-by-step explanation:

In the graph we have a piecewise function composed of a parabola and a line.

The parabola has the vertex in the point (0, 2) and cuts the y-axis in y = 2.

The equation of this parabola is $y = x ^ 2 +2$

Then we have an equation line $y = -x + 2
$

Note that the interval in which the parabola is defined is from -∞ to x = 1. Note that the parabola does not include the point x = 1 because it is marked with an empty circle " о ."

(this is $x< 1$ )

Then the equation of the line goes from x = 1 to ∞ . In this case, the line includes x = 1 because the point at the end of the line is represented by a full circle .

(this is $x\geq 1$ )
