Aparabola has a focus of f(β11,5) and a directrix of x=β12. the point p(x, y) represents any point on the parabola, while d(β12,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: step 1: fp=dp step 2: (xβ(β11))2+(yβ5)2ββββββββββββββββββ ββ=(xβ(β12))2+(yβy)2βββββββββββββββ βββββ step 3: x2+22x+121+y2β10y+25=x2+24x+144 step 4: y2β10y+2=2x step 5: 12y2β10y+1=x identify each incorrect step. select all answer choices that both state an incorrect step and explain why it is incorrect. if there is only one incorrect step, select "only" and the answer choice that states and explains the incorrect step.\ 1, step 3 is incorrect because he expanded the first binomial incorrectly. 2, step 5 is incorrect because a previous step is incorrect 3, step 2 is incorrect because he used the wrong signs for the coordinates of the focus. 4, step 3 is incorrect because a previous step is incorrect. 5, step 5 is incorrect because he divided incorrectly. 6, only 7, step 4 is incorrect because a previous step is incorrect.

If its non of them tell me..valerie took a day-trip. she drove from her house for a while and took a coffee break. after her coffee break, she continued driving. after 2 hours of driving after her coffee break, her distance from her house was 210 miles. her average speed during the whole trip was 60 miles per hour. valerie created the equation yβ210=60(xβ2) to represent this situation, where xx represents the time in hours from her coffee break and yy represents the distance in miles from her house. which graph correctly represents valerie's distance from her house after her coffee break?
