I think your answer would be C. This is because experimental probability has actually been tried out.

MariettaO [177]

Answer:

x = -21

Step-by-step explanation:

-5/4x - 2 = -1/4x + 19

subrtact the slope( constant, mx) from both sides

subtract a y-int ftom both sides

divde both sides by the remaining slope(constant or mx)

Nutka1998 [239]

Answer:

60.65

Step-by-step explanation:

The Law of Cosines can help you figure this out. Call the given sides "a" and "b" and the given angle "C". Then the third side, "c" will satisfy the relation ...

c² = a² + b² -2ab·cos(C)

= 33² +37² -2·33·37·cos(120°) = 3679

c = √3679 ≈ 60.65476 ≈ 60.65

The length of the third side is about 60.65 units.

If f(x) = x2, and<br> g(x) = x – 1, then<br> f(g(x)) = [? ]x2+[?]+ [?]

Basile [38]

Answer:

f(g(x)) = x² - 2x + 1

Step-by-step explanation:

To find f(g(x)), substitute x = g(x) into f(x) , that is

f(g(x))

= f(x - 1)

= (x - 1)² ← expand using FOIL

= x² - 2x + 1
