Answer:
1 over 2 is the slope :)
Step-by-step explanation:
Answer:
The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)
solve and get
(2.5,17.5)
or x= 2.5 y=17.5
Step-by-step explanation:
The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x
7x-x=15
6x=15
x=2.5
Then we can solve for y
y=7(2.5)
y=17.5

Answer: 3 1/2 ( mixed number)
Step-by-step explanation:
- First you have to put 3.5 into na fraction
- In a fraction it is 35/10
- as a mixed number, it would be: 3 5/10 ( a mixed number )
- Bur we still have to simplify so simplified would be: 3 1/2 ( mixed number)
Answer:
3.7
Step-by-step explanation:
