Answer:
x - 2y - 5= 0
i think is the answer for number 1 i hope it is
Yes he is correcct because 4/8 and 1/2 is the same thing
If she only had 1 hour sessions she had 8 sessions in the first week because if you do 35 times 8 you get 280.
This is an exponential function.
If x = 0, 2^x = 2^0 = 1. The beginning value of 2^x is 1 and the beginning value of 51*2^x is 51.
Make a table and graph the points:
x y=51*2^x point (x,y)
-- --------------- ---------------
0 51 (0,51)
2 51*2^2 = 51(4) = 204 (2,204) and so on.
The graph shows up in both Quadrants I and II. Its y-intercept is (0,51). Its slope is always positive.
