First ask yourselfhat needs to be dristributed.
That would be -1 (x-9)
To distribute you have to multiply the number out side of the parentheses (-1) by each term inside the parentheses( x and -9)
-1×x=-x
-1×-9=9
Now the expression is
-x+9+4x
To simplify you have to combine like terms (4x and-x)
4x-x=3x
Your answer is 9+3x or 3(3+x).
Answer:
15/2 or 7.5
Step-by-step explanation:

distribute 5/6 to each number

divide both sides by 5/6


7x+100+68.25 Let me know if you want me to explain it to you
Answer:
D) 
Step-by-step explanation:
Basically, if you plug in the x and y-coordinates into an equation, both sides should work out to be equal to each other:
Since
, we can eliminate choice A
Since
, we can eliminate choice B
Since
, we can eliminate choice C
Therefore, since
, then D is correct. Also,
