Answer:
Audrey can afford 4 hours of lesson.
Step-by-step explanation:
Given that:
Amount Audrey has to spend = $111
Cost of racket = $55
Cost per lesson = $14
Let,
y be the total cost
x be the number of hours
According to given statement;
y = 14x + 55
111 = 14x + 55
111 - 55 = 14x
14x = 56
Dividing both sides by 14
Hence,
Audrey can afford 4 hours of lesson.
6 (x - 5) = 4x + 20
6x - 30 = 4x + 20
6x - 4x = 20 + 30
2x = 50
x = 25
Answer:
limit does not exists.
Step-by-step explanation:
From the given graph it is clear that the function approaches to 4 when x is approaches to 2 from left. So,
The function approaches to -4 when x is approaches to 2 from right. So,
Now,
Since, left hand limit is not equal to right hand limit, therefore, limit does not exists.
