Answer:
if the x after the 20 means multiply then the answer is -34/7 or -4 6/7 if the x is a letter then it's 2/11
Step-by-step explanation:
20x2-7x=6
20x2=40
40-7x=6
subtract 40 from 6= 34
-7x=34
34÷-7= -34/7 if needed in a mixed fraction -4 6/7
Answer:
Step-by-step explanation:
Y = mx + b
-1/2 x + 3y = -3
3y = 1/2 x -3
y = 1/6 x - 1
Where slope m = 1/ 6and y intercept b = -1

Answer:
B
Step-by-step explanation:
![3 \times \frac{1}{2} = \frac{7}{2}](https://tex.z-dn.net/?f=3%20%5Ctimes%20%5Cfrac%7B1%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B7%7D%7B2%7D%20)
![1 \times \frac{7}{10} = \frac{17}{10}](https://tex.z-dn.net/?f=1%20%5Ctimes%20%5Cfrac%7B7%7D%7B10%7D%20%20%3D%20%20%5Cfrac%7B17%7D%7B10%7D%20)
7/2 - 17/10
35/10- 17/10
18/10
![\frac{18}{10}](https://tex.z-dn.net/?f=%20%5Cfrac%7B18%7D%7B10%7D%20)
1 8/10
1 4/5
Use the formula (y2-y1)/(x2-x1) from the coordinates
(3-9)/(8--7)
-6/15 reduce to get
-2/5 is the slope.
