Y=mx + b
M stands for the slope.
In this case it would be -2

Answer:

B) -2

Step-by-step explanation:

The general form of slope-intercept form is y = mx +b, where "m" is the slope and "b" is the y-intercept.

The given equation is y = -2x + 11

Now compare the given equation with the general form and find the value of slope (m).

By comparing, we get m = -2

So, the slope of the given equation is -2

A storage space in a basement is in the shape of a rectangular prisim. The hieght of the storage space is 5 feet. The length is

Greeley [361]

Answer:

length is 28.86ft

width= 4.12ft

Step-by-step explanation:

<h2>This problem bothers on the mensuration of solid shapes, a rectangular prism.</h2>

The storage space takes the shape of a rectangular prism, and we are required to find the width and length of the storage space.

let the width of the basement be "w"

Given data

volume v= $595ft^{3}$

length l = $7w ft$

width w= $w$

height h= $5 ft$

We know that the expression for the volume of a rectangular prism is

$volume= length * width* height$

substituting our data we have to find "w"

$595= 7w*w*5\\595=7w^{2}*5\\ 595= 35w^{2} \\$

dividing both sides by 35 we have

$w^{2}= \frac{595}{35\\} \\w^{2}= 17\\$

find the square root of both sides we have

$w=\sqrt{17} \\w= 4.12$

since we know that length= 7w and width = w , we can substitute our value for w and find the length and width

$length= 7*4.12= 28.86ft\\width = 4.12ft$

A new cell phone was $625 but it was reduced to $500. What was the percent of decrease?

zepelin [54]

Answer:

80%

Step-by-step explanation:

To find percent decrease (new amount/original amount)*100

(500/625)*100

=80

to check

625*.80

=500

625*80%

=500

Describe the differences between a parabola that has a horizontal directrix and a parabola that has a vertical directrix.

Readme [11.4K]

<span>A parabola that has a horizontal directrix is a parabola that opens up or down.

Here are some of its components:
1) Standard equation of a parabola with a horizontal directrix: (x-h)^2 = 4a(y-k),
a = distance from vertex to focus
2) Vertex at (h,k)
3) Focus(h,k+a)
4) Directrix: y = k-a
5) Axis of symmetry: x = h

A parabola that has a vertical directrix opens to the right or left and is on its side.

Here are some components
1) Standard equation of a parabola with a vertical directrix: (y-k)^2 = 4a(x-h)
2) vertex (h,k)
3) focus (h+a,k)
4) directrix: x = h-a
5) Axis of symmetry: y = k

Hopes this helps :)</span>
