Answer:


Step-by-step explanation:
Let
w ----> the amount of weight lost in pounds
we know that
The amount of weight Bernard lost plus the weight of this week must be equal to the weight of the last week
so
The linear equation that represent this situation is

solve for w
subtract 2,312 both sides

Answer:
Step-by-step explanation:
Given is a function



Average slope of this function is change of f(x) in (-2,6)/change of x in (-2,6)
= 
By mean value theorem there exists a c such that f'(c) = -18
i.e. 
Using quadratic formula
x = 2.61, -1.277
Out of these only 2.61 lies in the given interval
c = 2.61
Answer:
= -x+6
Step-by-step explanation:
we can simply substitute (x-4) in x place because when we say function of x , we are basically saying when we substitute a given value in the place of x we will find a given y.so for example if we have a question f(4), we can simply plug 4 to -x +2 so we will find y or f(x) = -2.
so the answer for the above question will be f(x)= -x +6.
Given :-
sam and Bethan shareare in the ratio 5:4 respectively.
Total no of money is = 54ÂŁ
Solution :-
Let Sams share is be x ie = 5
Let Bethans share be y ie = 4
Total no of share is = 9
Therefore the persons share is (particular persons share / total no of share) *
total value of money
Ans : -
Therefore sams share x is = (5/9)* 54 =30ÂŁ
Therefore Bethans share y is = (4/9) * 54 = 24ÂŁ
