PLZ HELP TIMED 20 POINTS! WILL MARK BRAINLIEST What is the equation of the graph below?

y = cosine (StartFraction x Over 0.4 EndFraction)
y = cos(5x)
y = cos(0.4x)
y = cosine (StartFraction x Over 5 EndFraction)

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.

If set d is not the empty set but is a subset of set e, then which of the following is true? d ∩ e = d d ∩ e = e d ∩ e = ∅

Which statements are true about box plots? check all that apply. they describe sets of data. they include the mean. they show the data split into four parts. they show outliers through really short “whiskers.” each section of a box plot represents 25% of the data.
