This means that (x-6)(x+2) = f(x) is the equation for the parabola due to that if you plug these in, when x=6 and x=-2 then y=0. Expanding it, we get
x^2+2x-6x-12=x^2-4x-12. Since the x coordinate of the vertex is -b/2a, it's 4/2=2
I’m not sure what 1. is sorry, but I think I know what 2 and 3 are.
2.) 120/1 x 3/4 because 3/4 is just the fraction form of 75%. Also 120/1 is just 120 as a fraction
3.) 1,200 x 0.03 because 0.03 is just the decimal form of 3%
Sport City is the better deal.
Sport City = 180 - (180 x .15) = $153
Tennis World = 200 - (200 x .20) = $160
The answer is A or the frist one since there really isnt letters
I got (2,-5)(-8-5)(2,19)(-8,19). Here's my step-by-step work! Hope everything makes sense! If not, feel free to comment back with any questions or concerns you have about my answers/work. :)
