Answer:
x=142, y=-360. (142, -360).
Step-by-step explanation:
5x+2y=-10
3x+y=66
----------------
5x+2y=-10
-2(3x+y)=-2*66
-----------------------
5x+2y=-10
-6x-2y=-132
-------------------
-x=-142
x=142
3(142)+y=66
426+y=66
y=66-426
y=-360
The answer is C. 6 times 4 is 24 and 1/4 times 4 is 1. therefore 24 + 1 = 25
Answer:
steps below
Step-by-step explanation:
y = (x-3) / x
replace x and y: x = (y-3) / y
y - 3 = xy
y - xy = 3
y(1 - x) = 3
y (f'(x)) = 3 / (1-x)

Answer:
(m) increased, (b) unchanged. g(x)
(m) decreased, (b) unchanged. m(x)
(m) unchanged, (b) increased. h(x)
(m) unchanged, (b) decreased. n(x)
f(x): m = -1/2 b = 2
g(x): m = 1/3 b = -3
h(x): m = 2 b = 0
