The focus of a parabola is (2,5) and the directrix is y=3. Find the equation of the parabola in standard form. A. Y= -x^2 /4 +x-5
B. Y= -x^2 /16 -x /8 -5 /4
C. Y= x^2 /4 -x+5
D. Y= x^2 /16 -x/4 +5/4

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

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

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
