What is the explicit formula for this sequence
-8, -3, 2, 7

a. an= -8+(n-)
b. an= -8+(n-1)5
c. 5+(n-)
d. 12+(n-1)5

Which of the choices shown could be used to prove that aacp=abcp ?

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0
