Answer:
-3
Step-by-step explanation:
If we directly evaluate the function at -1, we get 0/0, meaning we may still have a limit to find.
In this case, factoring the polynomial at the top would be helpful.
The polynomial can be factored to (x+1)(x-2), so the function would now turn out to be (x+1)(x-2)/(x+1)
The (x+1) cancel out, leaving you with (x-2), which you can directly evaluate by plugging in x as -1:
-1-2 = -3
Quick disclaimer: the function is still undefined at -1; it's just that the function gets closer and closer to -3 as you approach -1.
I hope this helped you.
Answer: I would say 135
Step-by-step explanation:
Answer:
1) -17x-9
Step-by-step explanation:
1)
(-2x^3+x-5)+(x^3-3x-4)
Combine like terms using P.E.M.D.A.S:
(-2x^3+x-5)+(x^3-3x-4)
(-9x-5)+(-8x-4)
Combine like terms:
(-2x^3+x-5)+(x^3-3x-4)
(-9x-5)+(-8x-4)
-17x-9
I hope this helps a bit!☺
The expression that shows how much money Mike will have left is : 42 + (-66.00).
Answer:
Step-by-step explanation:
Given a quadratic equation
ax^2+bx+c=0
you can find its solutions with the following formula:
x_{1,2} = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}
You equation is identified by the coefficients
x^2 - 3x + 5 \iff a = 1,\ b = -3,\ c = 5
Which means the solutions are
\dfrac{3 \pm \sqrt{9-4\cdot 5}}{2} = \dfrac{3 \pm \sqrt{-11}}{2}
