Step-by-step explanation:
definition of the derivative to differentiate functions. This tutorial is well understood if used with the difference quotient .
The derivative f ' of function f is defined ascthe above pic.
when this limit exists. Hence, to find the derivative from its definition, we need to find the limit of the difference quotient.
120 : 8 = 15
and 15 x 20 = 300, so the answer is C
Answer: 23
Step-by-step explanation:
1. Divide the amount Lynn paid for the ribbon, 17.25, by the amount the ribbon cost per foot, 0.75, to get how many feet of ribbon she bought.

Answer:
Given - 3 chairs + 5 tables = 7540 rs
TO find - Price of table
Solution -
Price of chair is Rs 220 ( given)
1 chair = 220
3 chairs = ?
3 × 220
660 Rs
660 rs + 5 tables = 7540 rs
5 tables = 7540 - 660
5 tables = 6880
1 table = 6880/5
= 1376 rs
Price of 5 Table is 6880 and 1 table = 1376 rs
21
half the height is 3
a=7
b=x
3(7+x)=84
21+3x=84
place the like terms on one side
84-21=3x
63=3x
x=21
