Question 26216: I don't understand the wording or what formula I need to plug this problem into. Find the equations of the circles that are tangent to the x axis and have a radius of length five units. In each case, the abscissa of the center is -3.(There is more than one circle that satisfies these conditions)

Question 26620: This is a word problem I am struggling with: You've been offered a part time job at a local retailer. You are being offered two different pay options:
Plan A: $18 an hour with overtime (above 20 hours/week) paying time and a half.
Plan B: $20 an hour with no over time.
I need to determine the algebraic formulas for plan A(x),(x being number of hours worked each week)and plan B(x) for a continuous domain of [0,40].
I have managed to figure out the plots for the graph but can't seem to wrap my head around the actual Algebraic formulas.

Question 26621: I have a question on transformations of graphs. I seem to have a little difficulty in finding the plots for graphs that are 'stretched' or 'shrunk'. For example: f(x)=x^2 is the basic quadratic function
g(x)= 2(x-1)^2+3 is the transformed function.
Do I solve g(x) by inserting the results from f(x) in for x into g(x) equation or do I solve g(x) by inserting the original x I used to solve f(x)? Also, is it correct to use BEDMAS and solve inside the brackets, then exponents then multiply?
Thanks a bunch

Question 26644: I am helping my son prepare for his algebra exam and have a couple of questions. 1) What is the difference between undefined slope and a slope of 0? 2) What is the range of the function y = -2X(Squared) + x when the domain is {1, 3, 5,}? I believe the answer to the second question is a simple as inserting the domain number for x and coming up with an answer of {-1, -15, and -45} but I am not sure.

Question 26754: please help solve the equation and graph on a number line. equation 3x+2=7x-6. this is how i did it. 3x=2-3x=7x-6-3x 2=4x-6 then i added 6 to 2 making 8 on the other side the 6 cancles out leaving 4x 4x divided by 4 leaves x on the other side 8 divided by 4 leaves 4 solution x=4 but when i check it the sides do not equal. thanks Sandra D.

Question 26996: In most businesses, increasing prices of their product can have a negative effect on the number of customers of the business. A bus company in a small town has an average number of riders of 800 per day. The bus company charges $2.25 for a ride. They conducted a survey of their customers and found that they will lose approximately 40 customers per day for each $.25 increase in fare.
Given the descriptions above, identify the graph of the function (line, parabola, hyperbola, or exponential), explain your choice, and give the domain and range of the function.

Question 27030: Here's the question-determine whether the equation represents a function, the equation is y^2=x+9. If I isolate y, my equation becomes y=3*sq root of x and it graphs as a function. The answer in the book says it's not a function because the equation is (y+1)^2=x. ????????
