Answer:
So what exactly is the question? bc it doesn't actually show a question
Step-by-step explanation:
9-2n=14 - 2n
Move -2n to the left side. Sign changes from -2n to +2n.
9-2n+2n= 14-2n+2n
9= 14-2n+2n
9= 14
Answer: no solution
Answer:
1.875
Step-by-step explanation:
The rate of change is the derivative of the function.

So, the rate of change is
f'(8) - f'(2) = - 0.625 + 2.5 = 1.875
Answer:
slope = - 44
Step-by-step explanation:
the derivative of f(x) at x = 3 is the slope of the tangent line
f(x) = -6x² - 8x + 5
differentiate using the power rule
f'(x) = - 12x - 8
f'(3) = - 36 - 8 = - 44 ← slope of tangent line at (3, 4 )
