Will give brainiesta parabola has a focus of f(−11,5) and a directrix of x=−12. the point p(x,y) represents any point on the parabola, while d(−12,y) represents any point on the directrix. miguel was asked to use the distance formula to write an equation to represent this parabola. here is his work: fp=dp step 1: √(x−(−11))2+(y−5)² = √(x−(−12))2+(y−y)² step 2: (x−(−11))2+(y−5)² = (x−(−12))2+(y−y)² step 3: x²+22x+121+y²−10y+25 = x²+24x+144 step 4: y²−10y+2 = 2x step 5: 1/2y²−10y+1 = x all the choices are it is multiple choice step 4 is incorrect because a previous step is incorrect. step 5 is incorrect because he divided incorrectly. step 1 is incorrect because he used the wrong signs for the coordinates of the focus. step 3 is incorrect because he expanded the first binomial incorrectly. step 3 is incorrect because a previous step is incorrect. step 5 is incorrect because a previous step is incorrect. step 2 is incorrect because the square roots cancel the squares. only

Brainiest and you will get 10 points! what is the value of p in the equation 4p + 3(p + 4) = 12p + 12? 12, 1, 0, -1. which of these is a simplified form of the equation 7x + 4 = 5 + 3x + 1x? 3x = 9, 3x = 1 , 11x = 9, 11x = 1 what is the value of z in the equation 3z + 5 = 4z − 8? 13, 1, -13, -1 the work of a student trying to solve the equation 3(4x − 2) = 9 + 2x + 5 is shown below: step 1: 3(4x − 2) = 9 + 2x + 5 step 2: 12x − 2 = 14 + 2x step 3: 12x − 2x = 14 + 2 step 4: 10x = 16 step 5: x = 1.6 in which step did the student first make an error and what is the correct step? step 2: 12x − 2 = 4 + 2x step 2: 12x − 6 = 14 + 2x step 3: 12x + 2x = 14 + 2 step 3: 12x − 2x = 14 − 2
