For starters, follow through this problem on the order of operations. PEMDAS is the one I use, but I’ve seen others. It stands for Parenthesis Exponents Multiplication Division Addition Subtraction. You can’t do anything inside the parenthesis and there are no exponents, so we skip to the multiplication. That -2 outside of the parenthesis is what you multiply by. So, your equation then becomes 7x -6x +12. Combining like terms, you are left with x + 12. If what are looking for is substituting -3 in for x, that’s also easy. Just put -3 in place of all the x’s and again follow through order of operations. 7(-3)-2[4(-3)-6] is what you should start off looking like. Doing your multiplication, you have -21 -2(-12-6). Go to your parenthesis, -21 -2(-18). Multiply, -21 + 36. And finally, add. If using substitution, your answer is 15. I did both equations because I didn’t know which way they were supposed to be drone because that x= -3 thing was confusing me. I hope this helped though. :)

F(x) = x(2x/2)/x(x+5)(x+6)^2 <br><br> Find the vertical asymptotes?
Alex Ar [27]

Answer:

  x = -5, x = -6

Step-by-step explanation:

After canceling common terms from numerator and denominator, there are two factors remaining in the denominator that can become zero. The vertical asymptotes are at those values of x.

\displaystyle F(x)=\frac{x\frac{2x}{2}}{x(x+5)(x+6)}=\frac{x}{(x+5)(x+6)}

The denominator will be zero when ...

  x + 5 = 0 . . . . at x = -5

  x + 6 = 0 . . . . at x = -6

Which equation could generate the curve in the graph below
Setler79 [48]
The curve has been attached and the answer choices are:

y = 3x² – 2x + 1

y = 3x² – 6x + 3

y = 3x²<span> – 7x + 1
</span>
The attached graph has a vertex in the first quadrant. Therefore, the coordinates of the vertex would be both positive.

Let's start with first equation:

                                               y = 3x² – 2x + 1

using the equation of axis:
                                            x = -b/2a
                                            x = 2/6
                                            x = 1/3
SUbstituting the value of x in the main equation to get the y-coordinate of the vertex.
                                               y = 3(1/3)² – 2(1/3) + 1
                                               y = 3/9 – 2/3 + 1
                                               y = 1/3 – 2/3 + 1
                                               y = (1 - 2 + 3)/3
                                               y = 2/3

Hence, the vertex would be:
                                             (h,k) = (1/3 , 2/3)

Also, the leading coefficient is positive, so the parabola would be concave up.

Thus the final answer choice will be:

                                             y = 3x² – 2x + 1
