Answer:
42 / 7 = 6
Step-by-step explanation:
There are 6 rows in the class room.
Answer:on which interval is the function increasing
Answer:(4, infinity
Step-by-step explanation:
Given :
When 7 is subtracted from five times a number, the result is greater than twice the sum of the number and 4.
To Find :
All the numbers that satisfy the inequality.
Solution :
Let , the number is x .
Mathematical expression for first term is :
5x - 7
Mathematical expression for second term is :
2(x + 4)
Now , comparing both the expression by given constrain.

So, all the numbers that satisfy the inequality are greater than 5.
Hence , this is the required solution.
Answer:
