The question is incomplete. Here is the complete question:

Denise earns $30 an hour. She wants to purchase a computer that costs $2000. Create and solve an inequality to determine the least amount of hours she must work in order to be able to purchase the computer.

Answer:

30h\geq 2000\ or\\h\geq67

Denise has to work at least 67 hours in order to buy a computer that costs $2000.

Step-by-step explanation:

Given:

Hourly earning of Denise is $30.

Let the number of hours Denise works be 'h'.

Now, total earning of Denise can be calculated using the unitary method and is given as:

Total\ money=\textrm{Hourly earning}\times \textrm{Total hours worked}\\Total\ money=30\times h\\Total\ money=30h

Now, total money earned by Denise must be at least $2000 in order to purchase a computer. Therefore, the inequality is given as:

30h\geq 2000\\h\geq \frac{2000}{30}\\h\geq 66.7

Therefore, Denise has to work at least 67 hours in order to buy a computer that costs $2000.

82. A company spends x hundred dollars on an advertising
crimeas [40]

The company spends $649 on advertising

The sales function after advertising is given as:

S(x) = 5 + 7\ln(x + 1)

When the total sales is $19,100, we have S(x) = 19100

So, the sales function becomes

5 + 7\ln(x + 1) = 19.1

Subtract 5 from both sides

7\ln(x + 1) = 14.1

Divide both sides by 7

\ln(x + 1) = 2.014

Take exponents of both sides

x + 1 = e^{2.014

x + 1 = 7.49

Subtract 1 from both sides

x= 6.49

Hence, the company spends $649 on advertising

Find x if 2^x=8^3x-8
Anon25 [30]

Step-by-step explanation:

First we have to same the bases.

As we know 8=2^3.

Replace 8 with 2^3.

Like this .

2^3x=2^3(2x+1).

Now 3x=3(2x+1) distribute 3 by the Barker.

3x=6x+3.

6x+3=3x.

6x-3x=-3.

3x=-3.

X=-1.
