Greg spent $4 on 5 packs of sport cards.

tino4ka555 [31]

Answer:

(a) Money spend on each pack will be $0.8

(b) Money send on each pack will be $0.2

Step-by-step explanation:

We have given that Greg spent $4 on 5 packs of spot card

(a) We have to find how much Greg spend on each pack

Cost of each pack will be $=\frac{4}{5}=$0.8$

(b) In this case it is said that Greg spent half of money

So money spent by Greg $=\frac{4}{2}=$2$

And he bought twice of pack than earlier

So number of packs he bought $=5\times 2=10$

So money spend on each pack will be equal to $=\frac{2}{10}=$0.2$

F(x)=x^2+9x-16 What is vertex Axis of semetry

UNO [17]

Answer:

axis of symmetry is $x=\frac{-9}{2}$ .

The ordered pair of the vertex is $(\frac{-9}{2},\frac{-145}{4})$ .

Step-by-step explanation:

Your function is a quadratic.

Compare $x^2+9x-16$ to $ax^2+bx+c$ .

You should see that $a=1,b=9,c=-16$ .

The x-coordinate of the vertex or the axis of symmetry since the axis symmetry goes through the vertex can be found by computing $\frac{-b}{2a}$ .

So here we go!

The axis of symmetry is $x=\frac{-9}{2(1)}=\frac{-9}{2}$ .

When you write your axis of symmetry be sure to write it as an equation.

That is the axis of symmetry is $x=\frac{-9}{2}$ .

Now that was also the x-coordinate of your vertex. To find the corresponding y-coordinate of the vertex, plug your value for $x$ into

$y=x^2+9x-16$ .

$y=(\frac{-9}{2})^2+9(\frac{-9}{2})-16$

Put into calculator:

$y=\frac{-145}{4}$ when $x=\frac{-9}{2}$

The ordered pair of the vertex is $(\frac{-9}{2},\frac{-145}{4})$ .
