Answer:
The correct answer is m = 2/1 because they first point it reaches is (1,2) and so you insert those numbers (x,y) into the rise and run equation (y/x) and get the answer 2/1.
Hope this helps!
(Hint: M = Slope)
It will be going down read it from left to right and it it goes up its positive if not its negative<span />
The sum of what, you need to explain more
Answer:
Subtractive Property of equality
Step-by-step explanation:
Since x = y, When you subtract anything from x, you must do the same to y for them to stay equal.
Answer:
x = 5, x = -5 are your answers
Step-by-step explanation:
First, FOIL (First, Outside, Inside, Last)
(x + 4)(x - 4) = 9
x(x) = x²
x(-4) = -4x
4(x) = 4x
4(-4) = -16
x² - 4x + 4x - 16 = 9
Simplify. Combine like terms
x² (-4x + 4x) - 16 = 9
x² - 16 = 9
------------------------------------------------------------------------------------
Isolate the x. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 16 to both sides
x² - 16 (+16) = 9 (+16)
x² = 25
Next, isolate the x completely by rooting both sides
√(x²) = √(25)
x = √25
x = √25 = √(5 x 5)
x = √25 = √(-5 x -5)
x = 5 , -5
------------------------------------------------------------------------------------------
x = 5, x = -5 are your answers
------------------------------------------------------------------------------------------
