What is a formula for the nth term of the given sequence? -5, -2,1...
1)an = -8 + 3n
2)an = -5 – 3(n-1)
3)an= -5 + 3(n + 1)
4)An = -5(3)"

Find the x coordinate of the point.

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.

50 plz, given the system of equations, match the following items. x + 3 y = 5 x - 3 y = -1 a) x-determinant b) y-determinant c) system determinant match the following to the pictures below.
