Multiply 3 1/2 by two because the distance was hiked twice, then add 2 3/8.

=(3 1/2 * 2) + 2 3/8
=7 + 2 3/8
=9 3/8 miles hiked total

ANSWER: 9 3/8 miles

Hope this helps! :)

Which of the binomials below is a factor of this trinomial? x2 - x-12 A) x+6 B) x+4 C) x-4 D) x-6
andre [41]
<h2>x² - x - 12</h2><h2 />

Start by setting up your two sets of parenthses.

X² breaks down into x and x.

What we are looking for is factors of the constant term

that add to the coefficient of the middle term.

The question is, what is the coefficient of the middle term

in this problem if there is nothing written in front of the x.

Well if there is nothing written there,

the coefficient is understood to be 1.

So what we are looking for are factors of -12 that add to -1.

<em><u>Factors of -12</u></em>

+12 · -1

-12 · +1

+6 · -2

-6 · +2

+4 · -3

-4 · + 3

We can see that -4 and +3 add to -1.

So they go in the second position of each binomial.

This gives us (x - 4)(x + 3) as our answer.

HELP !!!! can someone help me please how can i use the vertex formula to find this equation for this graph ?
DedPeter [7]
Based on that table of values, we know the highest point(vertex) is at 0.9, 5.9

we can also use just one another point... say 1.4, 4.6

\bf \qquad \textit{parabola vertex form}\\\\&#10;\begin{array}{llll}&#10;y=a(x-{{ h}})^2+{{ k}}&#10;\end{array} \qquad\qquad  vertex\ ({{ h}},{{ k}})\\\\&#10;-------------------------------\\\\

\bf \begin{cases}&#10;h=0.9\\&#10;k=5.9&#10;\end{cases}\implies y=a(x-0.9)^2+5.9&#10;\\\\\\&#10;\begin{cases}&#10;\textit{another point}\\&#10;x=1.4\\&#10;y=4.6&#10;\end{cases}\implies 4.6=a(1.4-0.9)^2+5.9&#10;\\\\\\&#10;4.6=a(0.5)^2+5.9\implies 4.6-5.9=a(0.5)^2\implies -1.3=a(0.5)^2&#10;\\\\\\&#10;\cfrac{-1.3}{0.5^2}=a\implies -5.2=a&#10;\\\\\\&#10;thus\qquad \qquad \boxed{y=-5.2(x-0.9)^2+5.9}
