Answer:

1 which is 0

Step-by-step explanation:

when referring quadratic equations solution is another word for zeros or x intercept.

And for finding what it is we can see it hit the x axis once at Y = 0.

Sloan [31]

1/3 of an hour = 20 minutes

8 hours = 480 minutes

So to find the number of periods we divide 480 by 20. Answer is 24

Write an equation for the graph below in terms of x

monitta

Answer:

x = y/2 - 1/2

Step-by-step explanation:

you can use the slope-intercept form of a line first, then change to terms of 'x'

y = mx + b where 'm' is the slope and 'b' is the y-intercept

if we use two points on the line, such as (-1, -1) (0, 1), we can find the slope

m = 1-(-1) / 0-(-1)

m = 2/1

b = 1

Slope-Intercept form: y = 2x + 1

in terms of 'x':

2x = y - 1

x = y/2 - 1/2

Margot is sewing a ribbon on a seam along the perimeter of a square pillow. The side length of the pillow is 2x2 1 inches. She p

Sauron [17]

The expression used for the length of ribbon that she needs for both pillows will be $4(2x^{2} +4x-6)$ .

The total length of the pillow she needs will be 130 inches.

Given,

The side length of pillow is $(2x^2 + 1) \ inches$ .

The side length of another pillow is $4x-7 \ inches$ .

We know that perimeter of square will be,

$P=4\times length$

So the perimeter of pillow will be,

$P=4\times (2x^2+1)\\$

$P=8x^{2} +4$

Similarly, the perimeter of another pillow will be,

$P=4\times (4x-7)$ ]

$P=16x-28$

Hence,the total length of ribbon that she needs for both the pillows will be,

$8x^{2} +4+16x-28\\8x^{2} +16x-24\\4(2x^{2} +4x-6)$

If $x=3.5\\$ then the total length of ribbon will be,

$4(2\times 3.5^{2}+4\times 3.5-6)\\4(2\times 12.25+14-6)\\$

$4(24.5+8)$

$4\times 32.5\\$

$130 \ inches$ .

Thus the required expression will be $4(2x^{2} +4x-6)$ and the total length of ribbon she needs will be 130 inches.

So, the correct option will be (D).
