Answer:
A
Step-by-step explanation:
Plug in -6 to the equation
-5 - 3(-6) > 10
Simplify for -5 + 18 = 13
13 > 10
Number 2. x=5/3 and y=5
number 4. x=7/3 and y=-5
that's all i could answer. and for number 1 x=-3
The answer is below hope it helps.
Perimeter of triangle = all sides added up
3a + 4 + 2a - 7 + 9a + 11
now add like terms
3a + 2a + 9a = 5a + 9a = 14a
4 - 7 + 11
= -3 + 11 = 8
so we have 14a + 8
as our simplest expression
X': (0,-6)
Y':(10,4)
Z':(-3,-1)
