Answer: D
Step-by-step explanation:
-4 < -w
w > -4
Since it doesn't have an equal sign, its an open circle. Since its greater than -4, it is going to the right, so shade right.
Answer is D
Well, in order to first determine the slope or y-intercept, you must put change the equation to this format: y=mx+b.
m=slope and b=y-interceptI
in order to do that, you must change this equation.
x+3y=9
-x -x
----------
3y=9-x
Then, rewrite it as:
3y=-x+9
_______
3 3
simplify to
y=-x/3 +9
Answer:
(2, 5)
Step-by-step explanation:
Rotation clockwise 90° can be accomplished by the transformation ...
(x, y) ⇒ (y, -x)
so
(-5, 2) ⇒ (2, 5)
Answer:
a^2 + 2ab + b^2 - c^2
Step-by-step explanation:
When you multiply all the terms together you get a^2 + ab + ac + ab + b^2 + bc - ac - bc - c^2. Then you can just combine like terms and simplify it to a^2 + 2ab + b^2 - c^2. Hope this helps :)
