Answer:
i think the answer is 8
Step-by-step explanation:
"three less than the quotient of 6 and a number (n=3) increased by nine"
(6÷3)-3+9
the quotient of 6 and 3 (6÷3) is 2
three less than 2: 2-3 which equals -1
increased by nine: -1+9 (which is also the same as 9-1) is 8
please don't hesitate to ask for clarification! hope i helped!
Well you have to change the first number in ALL of the () so
(-1,1) = (1,1)
(-2,-1) = (2,-1)
(-1,0) = (1,0)
so your answer is d <span>(1, 1), B(2, -1), C(1, 0)</span>
Answer
Find out the how far into the country does he go.
To proof
Let us assume that the total diatance travelled into the country be x .
Formula
![Time =\frac{Distance}{Speed}](https://tex.z-dn.net/?f=Time%20%3D%5Cfrac%7BDistance%7D%7BSpeed%7D)
As given
A cyclist rides into the country at an average speed of 10 miles per hour. When his bicycle gets a flat tire,
he walks it back at an average speed of 3 miles per hour.
If he returns home 6 and a half hours after he starts i.e the total time including the bike time and walk time of the cyclist be 6.5 hours.
Than the equation becomes
![\frac{x}{10} +\frac{x}{3} = 6.5](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B10%7D%20%2B%5Cfrac%7Bx%7D%7B3%7D%20%3D%206.5)
L.C.M of (10,3) = 30
Than the equation becomes
3x +10x = 195
solving
13x = 195
![x = \frac{195}{13}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B195%7D%7B13%7D)
x = 15 miles into the country
Hence proved
Answer:
x is less than or equal to 3
Step-by-step explanation:
The dot is a closed dot, which means that it is something or equal to, and the arrow is pointing down, which means less than. So the sign would be less than or equal to (sorry I don't have that sign on my computer). The dot is on three, so the inequality is x is less than or equal to 3.
