Answer:
see below
Step-by-step explanation:
The exponent rules that apply are ...
(a^b)(a^c) = a^(b+c)
a^-b = (1/a)^b
(a^b)^c = a^(b·c)
_____
These let you rewrite the given function as ...
f(x) = (3^(2x))(3^1) = 3(3^(2x)) = 3(3^2)^x = 3·9^x
and
f(x) = 3^(2x+1) = (3^-1)^(-(2x+1)) = (1/3)^-(2x+1)

Answer:
y = 2x + 2
Step-by-step explanation:
Notice that this line passes thru (-4, -6) and (2, 6). As we move from (-4, -6) and (2, 6), x increases by 6 and y increases by 12. Thus, the slope is
m = rise / run = 12/6 = 2.
From the graph we can see that the y-intercept is (0,2). Thus, the slope-intercept equation of this line is:
y = 2x + 2
Given that x is the number of chains;
7(4+3) = 7 * 7 = 49 feet
