3/5 divied by 1 5/9
3/5 times 9/14 =27/70
It already is simplified, youre answer is 27/70
X=1/3 or x=-2
explanation:
Find factors of 3 and 2 which subtract to make 5.
We should realise that (3x2) - 1 = 5.
Find the cross products and subtract to get 5. Add in the signs. One of the factors must be 0.

Step-by-step explanation:
Option A: y = 2x+3 is the right answer
Step-by-step explanation:
Given
slope = m = 2
Graph contains (-1,1)
The graph of a linear function can be written by using the slope-intercept form of equation given by:
![y = mx+b](https://tex.z-dn.net/?f=y%20%3D%20mx%2Bb)
Where
m is the slope and b is the y-intercept
So,
Putting the value of m
![y = 2x+b](https://tex.z-dn.net/?f=y%20%3D%202x%2Bb)
To find the value of b, putting the point (-1,1) in the equation
![1 = 2(-1) +b\\1 = -2 +b\\b = 1+2\\b = 3](https://tex.z-dn.net/?f=1%20%3D%202%28-1%29%20%2Bb%5C%5C1%20%3D%20-2%20%2Bb%5C%5Cb%20%3D%201%2B2%5C%5Cb%20%3D%203)
So the equation will be:
![y = 2x+3](https://tex.z-dn.net/?f=y%20%3D%202x%2B3)
Hence,
Option A: y = 2x+3 is the right answer
