Question 342395: Solve (for inequalities, write the solution in interval notation)
1. y/6-y/8=1
2. 3/5x>9 or 4x<-16
3. [2x-7]< 5 ( the sign is actually less than or equal to, i just didnt have a key to type it that way, and the brackets are actually absolute value signs)

Question 342420: Three points that form the vertices of a triangle are: (-4,3), (-7, -1), (3, -2)
Use the distance formula to determine if the triangle is a right triangle.
Please explain in detail how to get the answer.
Solution manual is saying to use the Slope calcualtion m = (y sub2 - y sub1) / (x sub2 - x sub1).
I thought the distance formula was d = square root of (x sub2 - x sub1) + (y sub2 - y sub1)???

Question 342423: Find the equation of a circle satisfying the conditions given. Then sketch the graph.
center (1, -2), diameter 6
if the radius is half of the diameter, wouldn't the radius be 3? The solution manual is saying the radius is 2 times the square root of 3.
Please explain in detail how to get the correct answer.
Thank you.

Question 342390: I am not sure if I am plugging in my test points correctly. FOr example on y<-x+1 I substituted 0 for x and y which gave me the answer 0<-1. I assume I should change that to 1>0 to put the x on the left side of the inequality? Is that correct? Can you just show me how you would work this, how you would enter test points and what the graph should look like in the end?
Thanks,

Question 343478: I really need help with this. I have never been in an algebra class until I started back to school. Any help that I can get to help me understand how this is to be worked would be greatly appreciated.
2. The coordinate graph of the backyard shows the location of the trees, plants, patio, and utility lines. If necessary, you may copy and paste the image to another document and enlarge it.
a. What are the coordinates of Tree A, Plant B, Plant C, Patio D, Plant E, and Plant F?
b. The water line is given by the equation
Imagine you want to put a pink flamingo lawn ornament in your backyard. You want to avoid placing it directly over the water line in case you need to excavate the line for repairs in the future. Could you place it at the point (-4,-10)?
c. What is the slope and y-intercept of the line in Part b? How do you know?
d. Imagine you want to add a sprinkler system and the location of one section of the sprinkler line can be described by the equation
Complete the table for this equation.
x y (x,y)
-5
-3
-2
4
5
e. What objects might be in the way as you lay the pipe for the sprinkler?

Question 343608: How do we find the points for the equation y=(1.2)^(-x)sinx
I mean can you please tell me step by step what I would have to do to find the value for y for each x point. Like in a table of values chart. X points are 0, 1, 2, 3, 4......How would we find the y values.
Thank You!
