Answer:
It is better to buy 20 g of flour 3 for 3.50
Step-by-step explanation:
It is given that 20g of 3 for 3.50
It means 3 packets of 20 g is 3*20 =60
So, 60g is for 3.50
So, 1 g ==0.05833 per gram.
Now, let's find unit rate for 40 g of 2 for 9.
2 packets of 40 gram = 2* 40 =80 grams
So, 80 grams costs 9
So, 1 gram = =0.1125
So, it is better to buy 20 g of flour 3 for 3.50
We can construct the function:
Where or
is ordinate and
is abscissa.
The function actually represents a line. Since it can have linear form.

Answer:
(A) The slope of secant line is 18.
(B) The slope of secant line is h+16.
Step-by-step explanation:
(A)
The given function is
At x=3,
At x=9,
The secant line joining (3,27) and (9,135). So, the slope of secant line is
The slope of secant line is 18.
(B)
The given function is
At x=5,
At x=5+h,
The secant line joining (5,55) and . So, the slope of secant line is
The slope of secant line is h+16.
