Answer:
It takes the frog 7 hours to get out of the well.
Step-by-step explanation:
We know that the well is 11 feet deep and the frog can climb 3 feet per hour.
Each time it climbs, it rests for an hour, and decreases its height by 1 foot.
So, if the frog reaches 3 feet in the first hour, then in the next hour it is 2 feet.
Lets calculate with the same pattern:
1st hour: 3 feet
2nd hour: 
feet
3rd hour: 
feet
4th hour: 
feet
5th hour: 
feet
6th hour: 
feet
5th hour: 
feet
6th hour: 
feet
7th hour: 
feet
Therefore, it takes the frog 7 hours to get out of the well.
Answer:
x=6 y=-3
Step-by-step explanation:
Answer:
Option B,C and E are solution to given inequality 
Step-by-step explanation:
We need to check which ordered pairs from given options satisfy the inequality
Ordered pairs are solutions to inequality if they satisfy the inequality
Checking each options by pitting values of x and y in given inequality
A ) (1, -5)
So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.
B) (-3, - 2)
So, this ordered pair is solution of inequality as it satisfies the inequality.
C) (0, -9)
So, this ordered pair is solution of inequality as it satisfies the inequality.
D) (2, -1)
So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.
E) (5, 4)
So, this ordered pair is solution of inequality as it satisfies the inequality.
So, Option B,C and E are solution to given inequality
513 * 40 + 513 * 6= 2052 + 3078 = 5130
