18+2 = 20

20x3=60

60-100= -40

3x(18-2)-100=-40

negative forty

Write a equation for the line parallel to

Llana [10]

Paralell has same slope
y=mx+b
m=slope
b=yint

same slope so other equation is
y=4x+b

input given point
(2,0)
x=2
y=0
0=4(2)+b
0=8+b
minus 8 both sides
-8=b

the equation is y=4x-8

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

Answer: Correct

Step-by-step explanation:

The conclusion is valid. Since $\overline{AB} \parallel \overline{DC}$ and $\overline{AD} \parallel \overline{BC}$ , we know that ABCD is a parallelogram because it has two pairs of parallel sides. Also, since $\overline{AB} \cong \overline{BC}$ , we know that ABCD is a parallelogram with a pair of consecutive congruent sides, making it a rhombus.
