Answer:

Step-by-step explanation:

So the diagram shows the weight of each puppy in pounds.

Each dot is a puppy.

The first dot is at 1/4 pounds meaning you have one dog that weights that much.

At the other end, you have 3 dots at 3/4 pounds meaning you have one dog that weights that much.

The heaviest puppy is 3/4 and the lightest is 1/4.

So dividing 3/4 / 1/4 = 3/4 * 4 = 3.

So 3 times as great

Suppose a parabola has an axis of symmetry at x=-5, a maximum height of 9, and passes through the point (-7,1). Write the equati

Nutka1998 [239]

the parabola has maximum at 9, meaning is a vertical parabola and it opens downwards.

it has a symmetry at x = -5, namely its vertex's x-coordinate is -5.

check the picture below.

so then, we can pretty much tell its vertex is at (-5 , 9), and we also know it passes through (-7, 1)

$\bf ~~~~~~\textit{parabola vertex form} \\\\ \begin{array}{llll} y=a(x- h)^2+ k\qquad \leftarrow \textit{using this one}\\\\ x=a(y- k)^2+ h \end{array} \qquad\qquad vertex~~(\stackrel{}{ h},\stackrel{}{ k}) \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \begin{cases} h=-5\\ k=9 \end{cases}\implies y=a[x-(-5)]^2+9\implies y=a(x+5)^2+9$

$\bf \textit{we also know that } \begin{cases} x=-7\\ y=1 \end{cases}\implies 1=a(-7+5)^2+9 \\\\\\ -8=a(-2)^2\implies -8=4a\implies \cfrac{-8}{4}=a\implies -2=a \\\\[-0.35em] ~\dotfill\\\\ ~\hfill y=-2(x+5)^2+9~\hfill$

Please help me solve this..<br>

Answer:

X<7. Graph 7. Then put a open circle and arrow it going left! And there you go.

Step-by-step explanation:

Add 18 to both sides. Since -2x has a negative, you flip the sign to less than instead of greater than.
