TIMED, does anyone know the answer?
77julia77 [94]

Answer:

D

Step-by-step explanation:

128/2 = 64

The squareroot of 64 = 8

That means that only C or D could be true; 8 is in the numerator not the denominator.

Look at the ys next. There are 5 in the denominator and 6 in the numerator. Five of them will cancel out leaving 1 in the numerator. That makes D the answer. However we should check out the xs.

There are 5 in the numerator and 7 in the denominator. That means that there are 2 left in the denominator. Since the xs are squared in the denominator, to remove the square root sign, you need to take out 1 x from under the root sign and throw the other one away.

Answer 8sqrt(y)/x

D

Write the quadratic function in standard formDetermine vertex and axes interceptsGraph it
jolli1 [7]

Step 1

Given;

f(x)=x^2+2x-8

Required; To find the vertex and axes intercepts. write it in standard form and graph it.

Step 2

Find the vertex

\begin{gathered} (h,k)=(\frac{-b}{2a},f(h)) \\ a=1,b=2,c=-8 \end{gathered}\begin{gathered} h=-\frac{2}{2(1)}=-1 \\ f(h)=(-1)^2+2(-1)-8=1-2-8=-9 \\ Vertex(h,k)=(-1,-9) \end{gathered}

Step 3

Find the axes intercepts

\begin{gathered} x^2+2x-8=0 \\ factors\text{ are 4x and -2x} \\ x^2+4x-2x-8=0 \\ x(x+4)-2(x+4)=0 \\ (x-2)(x+4)=0 \\ x=2\text{ or -4} \\ x-intercepts=(-4,0),(2,0) \end{gathered}\begin{gathered} To\text{ find the y-intercept set x=0} \\ f(x)=0^2+2(0)-8 \\ f(x)=-8 \\ y-intercept=(0,-8) \end{gathered}

Step 4

Graph the function.

Step 5

The standard form will be;

\begin{gathered} f(x)=ax^2+bx+c-\text{ Standard form of any quadratic eqaution} \\ Thus\text{ the required standard form will be;} \\ f(x)=x^2+2x-8 \end{gathered}
