They are equal
Answer:
-1
Step-by-step explanation:
lim x tends to 4 (x^2-9x+20)/(x-4). (x^2-9x+20)(x-4)=x-5.
So the limit is 4-5=-1
For a * = 2bc
for b * = 5ab
Answer:
Option B
Step-by-step explanation:
Given are three tables in x and y and we have to find which table shows a linear relation.
We know in a linear relation between x and y the graph would be a straight line and also the slope would be constant
i.e. change of y/change of x for any pair in the table would be a constant.
Out of three tables given, only second table satisfies this.
Hence B is the answer
