Solve for x

Mademuasel [1]

Answer:

x = 9

Step-by-step explanation:

Using the rule of exponents

$a^{m}$ × $a^{n}$ ⇔ $a^{(m+n)}$

Given

$11^{x}$ = $11^{4}$ × $11^{5}$ = $11^{(4+5)}$ = $11^{9}$

Since the bases on both sides are common, then equate the exponents

x = 9

Solve the inequality 3u+3(u+1)>2u+7 and write the solution in interval notation.

strojnjashka [21]

Given:

The given inequality is $3u+3(u+1)>2u+7$

We need to determine the solution of the inequality in interval notation.

Solution of the inequality:

The solution of the inequality can be determined by simplifying the inequality.

Thus, we have,

$3u+3u+3>2u+7$

$6u+3>2u+7$

Subtracting both sides by 3, we get;

$6 u>2 u+4$

Subtracting both sides by 2u, we have;

$4 u>4$

Dividing both sides by 4, we get;

$u>1$

Writing it in interval notation, we get;

$(1, \infty)$

Thus, the solution of the inequality is $(1, \infty)$
