PLS HELP!! The graph of a quadratic function f(x) = ax^2 + 12x + c has vertex (3,8). Find a and c

Ac contractor is building a new subdivision outside of the city. he has started work on the first street and is planning on the other streets to run in a direction parallel to the first. the second street will pass through (-2,4) find the equation of the location of the second street in standard form. a.2x+y=2 b. x-y=2 c.2x+y=2 d.x+y=2

Solve the equation - 2(m -30) = -6m a-15 b-13 c-8 d8

If 2(a^2+b^2)=(a+b)^2 then, > a+b=0, > ab=0, > a=b, > 2a=b
