Use the work shown to find the solutions of the quadratic equation.

-x^2 -x -3/4 =0
-x^2 -x = 3/4
-x^2 -x + [1/2]^2 = 3/4 + [1/2]^2
-x^2 -x +1/4 = 3/4 + 1/4

Which is a solution of x^2 -x -3/4 = 0?
O -1/4
O 1/2
O 3/2
O 3/4

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the answer is b

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
