If the endpoints of the diameter of a circle are (9, 4) and (5, 2), what is the standard form equation of the circle? a) (x + 7)2 + (y + 3)2 = 5 b) (x − 7)2 + (y − 3)2 = 5 c) (x + 7)2 + (y + 3)2 = 5 d) (x − 7)2 + (y − 3)2 = 5

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
