I would need a bit more to answer that one my friend
Answer:
x = 3
x < 3
Step-by-step explanation:
9x - 6 = 21
9x = 21 + 6
9x = 27
x = 3
9x - 6 < 21
9x < 27
x < 3
Easy. it’s b because when it’s all added up 9 is the answer
Answer:
OR 
Let's solve the equation step-by-step:
First, you must find the square root:
x = ± 
We know that 10 × 10 = 100 and -10 x -10 is 100
that means that the square root is either 10 or -10
And we also know that
are both 100
meaning that x =
OR 
If you put the formula into Y intercept form which is Y=M(slop)X + B(y int)
you will get
y = -1/2x + 2
B(y int) = 2
M(slope) = -1/2
plot (0,2) on graph then go down 1 left 2. put a point there repeat and connect dots.
