Find the axis of symmetry for this parabola y=-5x^2-10x-15 write it as an equation
Ksju [112]
Axis of symmetry is the x value of the vertex

the x value of the vertex, in form
y=ax^2+bx+c is -b/(2a)

so
y=-5x^2-10x-15
a=-5
b=-10

x value of vertex is -(-10)/(2*-5)=10/-10=-1
x=-1 is axis of symmetry

If wallpaper costs $1.25 per foot, how much will it cost to put new wallpaper in a room with area dimensions of 17 ft long by 16
alukav5142 [94]

Answer:

C. \$340

Step-by-step explanation:

Given wallpaper costs \$1.25 per square foot.

Also, the dimension of the room is 17\ ftlong by 16\ ft wide.

First, we will find the area of the room.

The room is in a rectangular shape.

So, the area of rectangle would be

       length\times width\\=17\times 16\\=272\ ft^2

Now, we will multiply this area with the cost of wallpaper.

As the cost of wallpaper is $1.25 per square foot.

The total cost of wallpaper for 272\ ft^2 would be 272\times 1.25=\$ 340
