Let f(x)=x^2+6x−16.<br> Enter the x-intercepts of the quadratic function in the boxes.

Sauron [17]

$\underline{\underline{\large\bf{Given:-}}}$

$\red{\leadsto}\:$ $\textsf{}$ $\sf f(x)= x^2+6x−16$

$\underline{\underline{\large\bf{To Find:-}}}$

$\orange{\leadsto}\:$ $\textsf{ x-intercepts of the quadratic function }$ $\sf$

$\\$

$\underline{\underline{\large\bf{Solution:-}}}\\$

$\longrightarrow$ x- intercept is the point where graph of given function touches the x-axis,f(x) becomes 0 at the point where graph of given function touches the x-axis. Therefore, we would to solve x^2+6x−16=0 and find its root.

$\begin{gathered}\\\implies\quad \sf x^2+6x−16=0 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf x^2+8x-2x −16=0 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf x(x+8)-2(x+8)=0 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf (x-2)(x+8)=0\\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf x=2\quad or \quad x=-8 \\\end{gathered}$

$\leadsto$ x-intercepts of the given quadratic function are 2 and -8 .

Karen runs 6 miles in 55 minutes. At the same rate, how many miles would she run in 44 minutes?

Anna007 [38]

Answer:

x = 4.363636...

Step-by-step explanation:

Set up a ratio

6 miles : 55 minutes

x miles : 40 minutes

Cross Multiply

55x = 40*6

55x = 240

55x / 55 = 240 / 55

x = 4.363636...

Can some help me please and thank you

Nadya [2.5K]

Your answer should be B 10m because 4x10=40 and that's the bxh then you need to divided by 2 do it would be 20. And 20m^2 is your answer so B is your answer

Is this right and what's the answer for number 3?

Mumz [18]

That looks great! But say you chose number 2. You could say you organized it by multiplying single packs by the pieces of packs.
