Answer:

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form"

A cyclist is riding a bicycle whose wheels have a diameter of feet. Suppose the wheels turn at a rate of revolutions per minute.

SCORPION-xisa [38]

Answer:

a.2010 rad/min

b.2412 feet/min

Step-by-step explanation:

We are given that

Diameter of wheel,d=2.4 feet

Radius,r= $\frac{d}{2}=\frac{2.4}{2}=1.2feet$

a.Rate=320 rev/minute

1 rev= $2\pi$ radian

320 rev/minute= $320\times 2\pi=640\pi radian/minute$

Where $\pi=3.14$

Angular speed= $640\times 3.14=2010 rad/min$

b.Speed,v= $r\omega$

$v=2010\times 1.2=2412 feet/min$

Which pair of numbers has a sum of 20 and quotient of 4

igomit [66]

Hi!

<h3>Let's use the guess and check method. </h3><h3>First, find numbers that when divided, equal 4, and are less than 20. </h3>

4/1 = 4
8/2 = 4
12/3 = 4
16/4 = 4

<h3>Now see if any of those pairs of numbers add up to 20. </h3>

4 + 1 = 5
8 + 2 = 10
12 + 3 = 15
<u>16 + 4 = 20</u>

<h2>The answer is 16 and 4.</h2>

Hope this helps! :)

HURRYYYY !!!!! The graph of f(x) = 2x is shown on the grid. The graph of g(x) = ()x is the graph of f(x) = 2x reflected over the

Tanya [424]

Reflecting through x=0 maps x to -x so

g(x) =f(-x) = -2x

Answer: y = -2x

Can't see the choices, look for a downward slope of two units down for every unit to the right, through the origin.
