A positive derivative means that the function is increasing.
Answer:
n=3
Step-by-step explanation:
you have 2n+7=6n-5
start with subtracting 2n from both sides giving you 7=4n-5
now take the -5 and add 5 to both sides, giving you 12=4n
now divide both sides by 4, now giving you 3=n
the variable has to be on the left every time you finish your work living with n=3

The value of 3a²-4ab-26² is -657
Answer:
Use the Triangle exterior angle theorem. The definition of this theorem, is that the exterior angle you are solving for is the sum of the two opposite interior angles. Set the equation:
80 + x = 3x - 22
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract x and add 22 to both sides.
80 (+22) + x (-x) = 3x (-x) - 22 (+22)
80 + 22 = 3x - x
Simplify.
102 = 2x
Isolate the variable, x. Divide 2 from both sides.
(102)/2 = (2x)/2
x = 102/2
x = 51
Check. Plug in 51 to the equation given.
80 + x = 3x - 22
80 + (51) = 3(51) - 22
131 = 153 - 22
131 = 131 (True).
