Answer: No, because an identity is an equation that is always true and cos(theta) - sin(theta) does not always equal 1.

Hope this helped! :)

Denise would like to purchase a computer that costs$2000. Create and solve an inequality in order to determine the least amount
photoshop1234 [79]

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.

PLEASE HELP!!! What is the slope parallel to 5x + y = 3, please show me step by step, will give the brainliest for this answer.
Andreas93 [3]

Answer:

-5

Step-by-step explanation:

First, put the equation into the form y = mx +b (where m is the slope and b is the y-intercept)

This would look like:

5x + y = 3\\y = -5x + 3

This means the slope is -5.

Parallel lines always have the same slope, so the slope of the parallel line is also -5
