The standard form for this equation would be y = 2x^2 - 4x -1. This can be computed by expanding first the (x - 1)^2 which is x^2 - 2x +1. Then this will be multiplied by 2 which will give us, 2x^2 - 4x +2. Lastly, we will deduct the 3 from the equation which gives us the final answer of y= 2x^2 - 4x -1.

Answer: See below.
Step-by-step explanation:
The formatting is likely incorrect for these two options:
y=(x−1)2, and
y = ( x − − 1 ) 2
I'll assume they were meant to be:
y=(x−1)^2, and
y = ( x + 1 )^2
In this case they would be non-linear, since y depends on the value of
Use a "^" sign to indicate raised to a power: x^2 means .
y=(x−1)2 means y = 2x - 2
y=(x−1)^2 means y =
Answer:
The second equation can be used
Step-by-step explanation:
Just plug in the values and the equation should look like this 8^2 + b^2 = 12^2
12 is the hypotenuse to plug that into c
and 8 is just a leg so you can either put it in a or b
Answer:
8.05 miles
Step-by-step explanation:
If it descended 2.2 miles to 5.85 miles then that means it was at 5.85 + 2.2 miles before its descent.
5.85 + 2.2 = 8.05
