Looks like the graph is decreasing to me
Step-by-step explanation:
5x can also be written as " -3x + 8x " so:
Using the distributive property:
Then again, using the distributive property (but in reverse):
The two numbers that the middle term should be split into in order to factor can be found by listing out pairs of factors for the product of the last term and the coefficient of the first term, and using the two factors whose sum is the middle term.
For eg (because that was a bit text heavy):
The product of the last term and the first coefficient (1 * (-24)) is -24
the factors of -24 include (and their sum)
-1, 24 (23)
1, -24 (-23)
-2, 12 (10)
2, -12 (-10)
-3, 8 (5)
3, -8 (-5)
-4, 6 (2)
4, -6 (-2)
The middle coefficient is 5 and the sum of the factors -3 and 8 are 5, so split 5x into -3x + 8x to be able to factor how I showed before.
Answer:
Option C.
Step-by-step explanation:
In the given data minimum value is 0.5 and maximum value is 6.5.
In option A and D, last interval is 4-6. It means 6.5 is not included in these histograms. So, option A and D are incorrect.
Now,
Class interval Students Number of students
0-3 B,C,D,F,G,J,K,L,M,N,O 11
3-6 E,H,I 3
6-9 A 1
Histogram plots number of hours spent listening to music daily on x axis and number of students on y axis. Height of the bar in the x interval 0 to 3 is 11, height of the bar in the x interval 3 to 6 is 3, and the height of the bar in the x interval 6 to 9 is 1.
Therefore, the correct option is C.

The ratio of the width to the length of a cell phone is 18 : 41.</h2>
Step-by-step explanation:
Given,
The length of a cell phone(l) = 82 mm and
The width of a cell phone(b) = 36 mm
Find, the ratio of the width to the length of a cell phone = ?
∴ The ratio of the width to the length of a cell phone
= 36 mm : 82 mm
= 36 : 82
Divided by 2, we get
= :
= 18 : 41
Thus, the ratio of the width to the length of a cell phone is 18 : 41.
