Answer:
Parallel
Step-by-step explanation:
The graphs of these two equations will never intersect. Hope this helps.
1. x + 2y -3 =0.
2. x/2 + y/9 = 1/3.
3. 4x-y+7=0.
4. x + y/2 = -1/2.
5. a. 3x-y-1=0.
b. x - y/3 = 1/3.
Answer:
38 miles
Step-by-step explanation:
Given,
The speed of Doreen = 9 miles per hour,
Since,
![Speed = \frac{Distance}{Time}\implies Distance = Speed\times Time](https://tex.z-dn.net/?f=Speed%20%3D%20%5Cfrac%7BDistance%7D%7BTime%7D%5Cimplies%20Distance%20%3D%20Speed%5Ctimes%20Time)
So, the distance covered by Doreen in 2 hours = 9 × 2 = 18 miles,
∵ Doreen speed is 90% of Irena's speed.
I.e. 90% of Irana's speed = 9 miles per hour
![\implies \frac{90}{100}\times \text{ Irana's speed}=9](https://tex.z-dn.net/?f=%5Cimplies%20%5Cfrac%7B90%7D%7B100%7D%5Ctimes%20%5Ctext%7B%20Irana%27s%20speed%7D%3D9)
,
Thus, the distance covered by Irana in 2 hours = 10 × 2 = 20 miles
Hence, the distance between their houses = distance covered by Doreen in 2 hours + distance covered by Irana in 2 hours
= 18 + 20
= 38 miles
To find the number of possible sandwiches made up of 1 bread type, 1 meat, and 1 topping, you would just multiply the numbers given (according to the "Fundamental Counting Principle"):
![3*4*7=84](https://tex.z-dn.net/?f=3%2A4%2A7%3D84)
There are 84 possible sandwiches.
To -120 feet all you have to do is multiply (-15) times 8
