Question number 1 You are comparing the costs of producing jewelry at two different manufacturers. Company 1 charges $3.25 per p

iece of jewelry plus a $400 flat fee. Company 2 charges $2.50 per pair piece of jewelry plus a $600 flat fee. How many pieces of jewelry are produced when the total costs for both companies are equal? Company 1 = $3.25x + 400 Company 2 = $2.50x+600 Solve the following equation to determine when the costs are equal 3.25x + 400 = 2.50x + 600 X=1333.33 DOC x=173.91 x=34.78 C O x=266.67

The value of x at equal total cost is 266.67

Here, we want to solve the equation to get the x-value that shows the total costs for the two companies are equal

We proceed as follows;

\begin{gathered} 3.25x\text{ + 400 = 2.50x + 600} \\ 3.25x-2.50x\text{ = 600-400} \\  \\ 0.75x\text{ = 200} \\  \\ x\text{ = }\frac{200}{0.75} \\ x\text{ = 266.67} \end{gathered}

an assembly line worker at Rob's Bicycle factory adds a seat to a bicycle at the rate of 2 seats in 11 minutes. Write a proporti
LuckyWell [14K]
Rate = 2 seats/11 minutes = 2/11  seats/min

Therefore the time required for s seats is
(m \, min) =  \frac{s \, seats}{ \frac{2}{11} \,  \frac{seats}{min} } =  \frac{11s}{2} \, min
That is,
m = (11s)/2 min

When s = 16, obtain
m =  \frac{11(16)}{2} = 88 \, min

When s = 19, obtain
m =  \frac{11(19)}{2} = 104.5 \, min

Answers:
m = \frac{11s}{2}
When s = 16, m = 88 min
When s = 19,  m = 104.5 min

Point m is located at 4,-2 what is located 2 units for point m
eimsori [14]

Answer:

None

Step-by-step explanation:

Given

m = (4,-2)

Required

Point 2 units from m

There are 4 possible points 2 units from m and they are:

m' = (4+2,-2) = (6,-2)

m" = (4,-2+2) = (4,0)

m'''= (4-2,-2) = (2,-2)

m'''' = (4,-2-2) = (4,-4)

From the graph, we have:

A = (4,2)

B = (-4,2)

C = (2,-3)

None of the points is 2 units from m

the midpoint is AB is M(3,-2). One endpoint is A(7,-9). Find the coordinates of the other endpoint B.
cestrela7 [59]

Answer:

<em>The required points of the given line segment  are ( - 1, - 5 ).</em>

Step-by-step explanation:

Given that the line segment AB whose midpoint M is ( 3, -2 ) and point A is ( 7, - 9), then we have to find point B of the line segment AB -

As we know that-

If a line segment AB is with endpoints ( x_{1}, y_{1} ) and  ( x_{2}, y_{2}  )then the mid points M are-  

<em>M = ( \frac{ x_{1} + x_{2} }{2} , \frac{ y_{1} + y_{2}  }{2}  )</em>

Here,

<em>Let A ( 7, - 9 ), B ( x, y ) with midpoint M ( 3, - 2 ) -</em>

then by the midpoint formula M are-

<em>( 3, - 2 )  = ( \frac{ 7 + x}{2} , \frac{ - 9 + y}{2} )</em>

On comparing x coordinate and y coordinate -

We get,

<em>( \frac{ 7 + x}{2} = 3  , \frac{ - 9 + y}{2}  = - 2)</em>

<em>( 7 + x = 6, - 9 + y = - 4 )</em>

<em>( x = 6 - 7, y = - 4 + 9 )</em>

<em>( x = - 1, y = -5 )</em>

<em>Hence the required points  A are ( - 1, - 5 ).</em>

<em>We can also verify by putting these points into Midpoint formula.</em>
