Answer:
We start with the equation:
(x^2 - 1)/(x + 1) = 2
We want to rewrite this in standard form.
We can multiply both sides by (x + 1) to get:
((x^2 - 1)/(x + 1))*(x + 1) = 2*(x + 1)
x^2 - 1 = 2*(x + 1) = 2*x + 2
Now we can move all the terms to one side to get:
x^2 - 1 - 2 - 2*x = 0
x^2 - 2*x - 3 = 0
And this is a standard quadratic equation, that we can solve by using the Bhaskara's formula, this will give us the solutions:
Then the two solutions are:
x = (2 + 4)/2 = 3
x = (2 - 4)/2 = -1
Answer:
C. $32.09, since it's not the fixed cost, it changes based on how much drinks are purchased.
The slope of the line is going to be 0.25m, since the 0.25 is the cost per mile and will change as more miles are added.
the delivery fee is always going to stay the same, so that will act as the “y intercept”
t = 0.25m + 3
-6 I'm pretty sure, any number that's positive times a negative is a negative, so just do 2x3 and then add the negative.
The answer is 4x2-5x;Area= 114 in<span>2 i think</span>
