You turn the negative to a positive like,
-5 - (-7) = 5 + (7)
= (12)
Since it's multiplication we can Multiply the constants. In this case 4, 15, and 2. We get 120. We now then multiply the variables. We then get the answe 120mnx
Answer:
1/3
Step-by-step explanation:
The slope is equivalent to:
(y₂-y₁)/(x₂-x₁)
Now we plug in the coordinates into the equation:
(7-6)/(5-2)=1/3
Answer:
3, -3, 0
Step-by-step explanation:
The exlcusions of x are where the denominator =0
So we can write the following equations
x²-9=0
and
5x=0
Let's solve the first one
x²-9=0
x²=9
x= ±3
and
5x=0
x=0
Therefore x cannot equal 3, -3, 0
