I think there's an error with this question. Mind to check it back and tell me the detail?
Answer:
7.
A.) -⅔
B.) 3/-2
Step-by-step explanation:
from 1 to -1 you have to go down 2
from 2 to -1 you have to go down 3
therefore your slope is -⅔
from 3 to 6 you go up by 3
from 1 to -1 you go down by 2
therefore your slope is 3/-2
Answer:
15x*45 i think
Step-by-step explanation:
Answer:
10x^3 + 6x^2 + 5x + 3
Step-by-step explanation:
F(x)=(5x+3)(2x^2+1)
= 5x*2x^2 + 5x*1 + 3*2x^2 + 3*1
= 10x^3 + 5x + 6x^2 + 3
= 10x^3 + 6x^2 + 5x + 3
In the given question, we come to know that Sammy sold 5 bottles for every 3 water bottles sold by David. In this case we get the ratio as 5:3
Now this ratio indicates that the total number of bottles can be divided into 8 parts for finding out a single part. the total number of water bottles that are sold by Sammy and David together are 160.
Now on dividing this total number of bottles by 8 we get the 20 as one part.
The,
Number of Bottles sold by Sammy = 5 * 20
= 100
Number of bottles sold by David = 3 * 20
= 60
So Sammy sold 100 water bottles and David sold 60 water bottles from the total of 160 water bottles.
