Answer:
Step-by-step explanation:
Y = -x -1..........(1)
y = -2x + 7....(2)
Equating the two equations
-x -1 = -2x + 7
-x + 2x = 7+1
x = 8
Putting x in (1)
y = -8 - 1
y = -9
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:

Thank you, have a good day! =)
Answer:
r<=-8 or r is less than or equal 8
Step-by-step explanation:
-2r+3>=19
-2r>=16
r<=-8
you flip the sign when the variable is a negative. To plot this on a number line place a close circle on -8 moving to the left direction.
