What is the equation in slope-intercept form that passes through the points<br> (0,4) and (-2,0).
Radda [10]

Answer:

slope intercept form is y=mx+b.  

The "m" in slope intercept form is the number that represents the slope of the line.  Think "m for movement" from any point to another.

The "b" in the equation is number that is the y-intercept.  The y-intercept is the y-value when x = 0, or where the line crosses the y-axis.  think "b for begin" on y-axis.

Substitute the numbers given in the problem into the form of the equation.  

m is 4

b is 2  

leave the x and the y because you need them so you can have a representation of all the points on the line.

Given: f(x) = X^2 - 3 and g(x) = X + 1 The composite function g°f is:_______.
LenKa [72]

Answer:

x² - 2

Step-by-step explanation:

To obtain (g ○ f)(x), substitute x = f(x) into g(x), that is

g(x² - 3)

= x² - 3 + 1

= x² - 2

Nastasia [14]
Well, a polygon is just a generic shape. Triangle, Quadrilateral, Pentagon,Hexagon, Octagon, Decagon, etc. Sides are the lines that meet to make up the polygon, and vertices are the corners where the sides meet. Here are some examples: 

<span>Triangle Quadrilateral (square, rectangle) </span>
<span>3 sides 4 sides </span>
<span>3 vertices 4 vertices </span>

A company manufactures a large number of rods. The lengths of the rods are normally distributed with a mean length of 4.4 inches
Elza [17]

Answer:

0.78814

Step-by-step explanation:

We solve using z score

z = (x-μ)/σ, where

x is the raw score = 4.0 inches

μ is the population mean = 4.4 inches

σ is the population standard deviation = 0.5 inches

z = 4.0 - 4.4/0.5

z = -0.8

Probability value from Z-Table:

P(x<4.0) = 0.21186

P(x>4.0) = 1 - P(x<4.0)

= 1 - 2.1186

= 0.78814

The probability that the rod you chose will be greater than 4.0 inches is 0.78814.
