Answer:
D. The city's population is decreasing at a rate of 15 people each year.
Step-by-step explanation:
We presume x=0 in 2005, so the population in 2005 is ...
P(0) = -15·0 +53,708 = 53,708 . . . . . . not 53,703
__
In 2011, the population would correspond to that for x=6, so would be ...
P(6) = -15·6 +53,708 = 53,618 . . . . . . not 53,813
__
The x-coefficient of -15 means that when x increases by 1, the population decreases by 15. The population <em>decreases</em> by 15 each year, not <em>increases</em>.
Answer:
The expressions are not equivalent because Negative 3 (2) (5 minus 4) + 3 (2 minus 6) = negative 18 and Negative 12 (2) minus 6 = negative 30
Step-by-step explanation:
Apparently, we're trying to see if ...
-3(x)(5 -4) + 3(x -6) = -12(x) -6
by evaluating the expressions for x=2:
-3(2)(5-4) +3(2 -6) ?= -12(2) -6
-6 -12 ?= -24 -6
-18 ≠ -30 . . . . . . . . . shows expressions are not equivalent
__
This demonstration matches the one in the first choice:
The expressions are not equivalent because Negative 3 (2) (5 minus 4) + 3 (2 minus 6) = negative 18 and Negative 12 (2) minus 6 = negative 30

i hope it helps you
Okay... so the y intercept it automatically 9. so that's out of the way. Now you narrow it down to a or b. the first number, with x is -3x. Thats your slope. easy as that
