Answer:
(b) (-3, -1)
Step-by-step explanation:
Differences between adjacent f(x) values are ...
-31, -13, -1, +5, +5, -1, -13
The function is increasing on intervals where the differences are positive: between (-3, -11) and (-1, -1). That is ...
f(x) is increasing on (-3, -1)
The answer in simplest form would be 5/6
Answer:
c
Step-by-step explanation:
Answer:
A. (-7 -2)
Step-by-step explanation:
You can eliminate y by multiplying the first equation by 7 and subtracting 6 times the second equation:
7(-3x +6y) -6(5x +7y) = 7(9) -6(-49)
-21x +42y -30x -42y = 63 +294 . . . . eliminate parentheses
-51x = 357 . . . . . . . . collect terms
x = -7 . . . . . . . divide by -51. This matches answer choice A.
