Equality Properties

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality
Subtraction Property of Equality

Step-by-step explanation:

Step 1: Define

3 - 4r ≥ 15

Step 2: Solve for r

[Subtraction Property of Equality] Subtract 3 on both sides: -4r ≥ 12
[Division Property of Equality] Divide -4 on both sides: r ≤ -3

Step 3: Compare

Substitute in r: -3 ≤ -3

This is true. -3 is less than or equal to -3.

What is the value of (2/3)^-4 A. -81/16 B. -16/81 C. 16/81 D. 81/16

Alisiya [41]

For this case, we must find the value of the following expression:

$(\frac {2} {3}) ^ {- 4}$

By properties of powers we have that:

$a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}$

Thus, we can rewrite the expression as:

$\frac {1} {(\frac {2} {3}) ^ 4} =\\\frac {3 ^ 4} {2 ^ 4} =\\\frac {81} {16}$

So, we have to:

$(\frac {2} {3}) ^ {- 4} = \frac {81} {16}$

Answer:

$\frac {81} {16}$

Option D
