This is false... you can get an easy example: (-2) + (10) = 10 - 2 = 8
Answer:
A) The 75 is the initial number of cells, and the 2 indicates that the number of cells doubles every minute
Step-by-step explanation:
When x=0 (no minutes have elapsed), the value of the function is ...
f(0) = 75(2^0) = 75(1) = 75 . . . . the initial number of cells
As x increases by 1 (minute), the number of cells is multiplied by 2, so the 2 is the multiplier each minute. It indicates the number doubles. ("double" = "multiply by 2")
x is not defined, but for the function to make any sense, it must represent elapsed minutes.

oh i thought i knew this sorry man
Step-by-step explanation:
Answer:
a. dbc = 66, ABC = 132
b. abd = 52, dbc= 52
Step-by-step explanation:
just remember that bisects means that the angles on either side of the middle line are equal. so for a, dbc = abd and ABC = 2x 66
for b, abd and dbc are equal, so both of them are just 104 divide by two
