3x+15=3(x+5) help please?

UkoKoshka [18]

3x+15=3(x+5)

3x+15=3x+15

3x-3x=15-15

Therefore x can be equal to any value.

a point on the rim of a wheel moves with a velocity of 80 feet per second. What is the angular velocity of the point if the diam

valentina_108 [34]

The angular velocity is 16 radians per second

<u>Solution:</u>

The angular velocity of point is given by formula:

$w = \frac{v}{r}$

Where,

w is the angular velocity in radians

v is the linear velocity

r is the radius

Given that diameter of wheel is 10 feet

$radius=\frac{diameter}{2}$

$radius = \frac{10}{2}=5$

Thus radius is 5 feet

A point on the rim of a wheel moves with a velocity of 80 feet per second

Linear velocity = v = 80 feet per second

Therefore, angular velocity is given as:

$w = \frac{80}{5} = 16$

Thus angular velocity is 16 radians per second

What is the equation of the following line? Be sure to scroll down first to see all answer options. (0,3) (3,0) A. y = -x + 3 B.

qaws [65]

The correct answer is Choice A.

If you plot the points on a graph, you will see that there is a slope of -1 and the y-intercept is (0, 3).

This matches the equation of y = -x + 3 in Choice A.
