Use the method of completing the square to write the equation of the given parabola in this form:

(y-k)=a(x-h)^2

where a is not equal to 0, (h, k) is the vertex, and x=his the axis of symmetry

find the x-intercept of the parabola with vertex (1,1) and y-intercept (0,-3). write your answer in this form: (x1,,y2)

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
