Y = -1x + b
Plug in equation
-6 = -1(2) + b
-6 = -2 + b, b = -4
Solution: y = -1x - 4
Its just now (m + n) so it would be *4 since *2 + *2
The answer is 40 because if you multiply 4 times per week× for 10 weeks=40 times for ten weeks.
The questions where asking to compute for the derivative of x->a, and base on my own calculation and further computation about the said function, the derivative of x->a is <span>\[f'(x)=-6x-5\] and if you replace x by 1 here you will get
\[f'(1)=-11\]. I hope you are satisfied with my answer and feel free to ask for more </span>
