Answer:

2 ≤ x < 9 or x = [2, 9)

Step-by-step explanation:

Negative four is at least six less than a number

-4 ≤ x - 6 ⇒ x ≥ 2

Sum of a negative two & nine times a number is less than seventy nine

-2 + 9x < 79 ⇒ 9x < 81 ⇒ x < 9

Combined inequality:

2 ≤ x < 9 or x = [2, 9)

balu736 [363]

Answer:

The answer is 3.

Step-by-step explanation:

Given that the Indices Law is,

${a}^{m} \div {a}^{n} = {a}^{m - n}$

${a}^{0} = 1$

So the expression is :

$3 \times {5}^{2} \div {5}^{2}$

$= 3 \times {5}^{2 - 2}$

$= 3 \times {5}^{0}$

$= 3 \times 1$

$= 3$
