Question 466393: solve the equation for y, (I am not to use any mixed number is my answer). Then I must find three solutions for the equation and graph it.
6y + 11x = -11
My first step is to isolate y, so therefore I believe I need to take away 11x from both sides.
Which leaves me with 6y = -11 - 11x and then I need to divide by 6
this is where i get confused. y = -11/6 - 11/6 x Im unclear as to this step

Question 467213: Now we can start from the graph of y = x^2, and use transformations to graph f(x) = - 2(x - 1.5)^2 + 6.5. Here are the steps:

Graph y = x^2
Shift it 1.5 units to the right to obtain the graph of y = (x - 1.5^2)
Reflect it over the x-axis to get the graph of y = - (x - 1.5^2)
Stretch it by a factor of 2. This will be the graph of y = - 2(x - 1.5^2)
Finally, move the function 6.5 units up to get the graph of f(x) = - 2(x - 1.5)^2 + 6.5

I look forward for your graph for this problem.
