Solve the inequality 3u+3(u+1)>2u+7 and write the solution in interval notation.
strojnjashka [21]

<u>Given</u>:

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

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

<u>Solution of the inequality:</u>

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)

The population of a city is expected to decrease by 6% next year. If x represents the current population, write an expression th
Kaylis [27]

Given:

Current population = x

The population of a city is expected to decrease by 6% next year.

To find:

The expression that represents the expected population next year. ​

Solution:

We have,

Current population = x

Decrease rate = 6%.

Expected population next year = Current population - 6% of Current population

                                                    =x-\dfrac{6}{100}x

                                                    =x-0.06x

                                                    =0.94x

Therefore, the expression for the expected population next year is 0.94x.
