High School Quadratic, standard and standard form of a curve
ohhh ok that makes sense thank you for making it more clear so the almost final will look like this 43=A(15625)+B(625)+C(25)+D then you divide them ?? -

High School Quadratic, standard and standard form of a curve
ya that's what it is, there are 4 points on the curve so like (x_1,y_1)=(25,43) is what i was thinking but that's only one point -

High School Quadratic, standard and standard form of a curve
so how would i put the points of A into y(x)=Ax^3+Bx^2+Cx+D cause there are 2 points and only 1 A -

High School Quadratic, standard and standard form of a curve
the curve points are: a) (25, 43) b) (28, 46) c) (32, 47) d) (35, 45) would i use y=mx+b i think that's a straight line -

Radius and coord of center of a circle
i don't know what half of 2/3 is or 4/3 because if i know that then i can square them and that's it i calculated : (x² - 2/3x + 1/9) + (y² + 4/3 + 2/3) = 22/9 is this it- lucifer_x

Radius and coord of center of a circle
Homework Statement 9x² + 9y² - 6x + 12y - 22 = 0 Homework Equations The Attempt at a Solution i got this far but can't finish i don't know what to do: 3(3x² - 2x + 1) + 3(3y² + 4y + 4) = 40- lucifer_x
