Step-by-step explanation
-2x+7y=16 x=-8,0 y=0,16/7
8x-6y=24 y=(3,0) x=(0,-4)
Each angle would be 160 degrees. to get the answer to this you take the number of sides (n) and subtract 2 then multiply by 180 and divide by n
Answer:
![8 - 3x > -25 : \left[\begin{array}{ccc}solution: x < 11\\Interval Notation:(-\infty,11)\end{array}\right]](https://tex.z-dn.net/?f=8%20-%203x%20%3E%20-25%20%3A%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dsolution%3A%20x%20%3C%2011%5C%5CInterval%20Notation%3A%28-%5Cinfty%2C11%29%5Cend%7Barray%7D%5Cright%5D)
Step-by-step explanation:
Subtract 
from both sides:
Simplify:
Multiply both sides by 
(reverse the inequality):
Simplify:
Divide both sides by 
:
Simplify:
Hope I helped. If so, may I get brainliest and a thanks?
Thank you, have a good day! =)
Answer:
y=2
x=3
Step-by-step explanation:
make x - y = 1 into x= y + 1
put that wherever x is in the other equation
so y + 1 + 2y =7. then combine like terms into 3y =6. then divide 6 by 3 so you get y = 2
then substitute 2 into the y in the equation x - y = 1 and you get x = 3
