Which represents the solution set to the inequality ? x –1 x x is greater than or equal to StartFraction 7 Over 16 EndFraction.

Vikentia [17]

Inequalities are used to represent unequal expressions.

The solution set to $\mathbf{x \ge \frac{7}{16}}$ is: $[\mathbf{\frac{7}{16}, \infty)}$

The inequality is given as:

$\mathbf{x \ge \frac{7}{16}}$

From the inequality above, we have the following observation.

The value of variable x starts from 7/16 (inclusive)
The value of variable x has no end (i.e. infinity)

Because, 7/16 is inclusive of the values of x, we make use of the open square bracket i.e. [

We treat $\infty$ , as an exclusive value. So, we make use of the close parenthesis i.e. )

Hence, the solution set is: $[\mathbf{\frac{7}{16}, \infty)}$

Which equation is an example of the commutative property of multiplication? (4 2i) = (2i 4) (4 2i)(3 – 5i) = (3 – 5i)(4 2i) (4 2

kozerog [31]

Option B is correct. (4 + 2i)(3 – 5i) = (3 – 5i)(4 + 2i) satisfies the commutative property of multiplication

Given two values A and B, according to the commutative property of multiplication;

AB = BA

This shows that the product of A and B stays the same no matter the arrangement.

From the given option, we can see that (4 + 2i)(3 – 5i) = (3 – 5i)(4 + 2i) satisfies the commutative property of multiplication where we can say;

A = 4 + 2i and B = 3 - 5i
