Step-by-step explanation:
There are a few steps to follow when you add or subtract rational expressions with unlike denominators.
To add or subtract rational expressions with unlike denominators, first find the LCM of the denominator. The LCM of the denominators of fraction or rational expressions is also called least common denominator , or LCD.
Write each expression using the LCD. Make sure each term has the LCD as its denominator.
Add or subtract the numerators.
Simplify as needed.
<h2>
Answer:</h2>
True
<h2>
Step-by-step explanation:</h2>
For any function of the form:
The coefficient produces a transformation called a reflection in the x-axis whenever , that is, this axis is said to be a mirror. Let's take an example, suppose you have a function:
If the leading coefficient is now -4, then the graph is reflected and the new function is:
This is shown in the figure below. The red parabola represents and the blue parabola is . As you can see, the red parabola has been reflected and transformed into the blue one.
Answer:
<h2>
2/81</h2>
Step-by-step explanation:
Probability is defines as the likelihood or chance that an event will occur.
Probability = expected outcome of event/total outcome.
Since a single die with 9 sides was rolled, the total event outcome will be 9*9 = 81
Expected outcome will be the event that the sum of the two rolls equals 3. The possible outcomes are {(1,2), (2,1)}. The expected outcome is 2
Probability that the sum of the two rolls equals 3 = 2/81
Hi! The answer is 0.60x + 25 because she charged $25 for the service and 0.60 per page. I hope this helps, Goodluck :)
