Find the vertex form of the equation y=3(x-2)squared -(x-5) squared

Eric has challenged himself to walk 24,000 steps in 4 days. if eric walks the same number of steps each day, which function represents the number of steps eric still needs to walk to reach his goal with respect to the number of days since he started his challenge? a. y = 8,000x − 24,000 b. y = -8,000x + 24,000 c. y = 6,000x − 24,000 d. y = -6,000x + 24,000

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 9 + 12x + 4x^2

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14
