Answer:
x = (14,15,16,,,,,,n)
Step-by-step explanation:
Here,x belongs to set of natural number N
and Condition given for set is " x is greater than 13 "
Now, N=(1,2,3,4,5,6,,,,n) and given that x > 13.
thus, x = (14,15,16,,,,,,n)
Let us assume the common ratio = x
Then from the given question we can write
7x + 2x = 450
9x = 450
x = 450/9
= 50
Then the quantity 450 grams can be divided in the ratio of 7 : 2 by = 7x:2x
= (7 * 50) : (2 * 50)
= 350:100
I hope this is the answer you were looking for and the procedure for finding the answer is also absolutely clear to you.
Answer given in the picture above.
Answer:
between x=-1.5 and x = 0
between x = 0 and x = 1.5
Step-by-step explanation:
For the interval -1.5 < x < 1.5, we can see that the slope is negative (i.e from top left to bottom right). Hence it can be said that the graph is decreasing during this interval.
For the other parts of the graph (as shown) the slope is positive (i.e from bottom left to top right). in those areas, the graph is increasing.
