Answer:

A pair of socks is two socks, therefore a pair of verticle lines would be two vertical lines. A verticle line is the y intercept on the graph, or a stright line going from the floor to the roof. Your legs for example is a pair of verticle lines.

For what values of x will (x, y) be a solution of the system of equations below: y = x2 + 3x -3 2x - 1 = y
ozzi
 hello : 
<span> y = x2 + 3x -3.... (1)
 2x - 1 = y ..........(2)
subsct in (1) : 
2x-1 = x² +3x -3
x² + x -2 = 0
(x+2 )(x-1 ) = 0
x+2=0 or x-1 = 0
x=-2 or x=1
if : x = -2     y = 2(-2)-1 =-2
if : x = 1      y = 2(1)-1 = 1

A-Plus Printers charges a one-time fee of $26 plus $.12 per flyer to print and deliver
Lena [83]

for 201 onwards we will see that the cost in A-Plus Printers less than the cost at Print-and-More

<h3>For how many flyers is the cost at A-Plus Printers less than the cost at Print-and-More?</h3>

A-Plus Printers charges $26 plus $0.12 per flyer, so if you print x flyers, the total cost is:

f(x) = $26 + $0.12*x

For Print-and-More, they charge only $0.25 per flyer, so here the equation is:

g(x) = $0.25*x

Here we need to see for which value of x the costs are the same:

f(x) = g(x)

$26 + $0.12*x =  $0.25*x

Now we can solve that linear equation for x:

$26 = $0.25*x - $0.12*x

$26 = $0.13*x

$26/$0.13 = 200

This means that for 200 flyers, the cost is the same in both places, then for 201 onwards we will see that the cost in A-Plus Printers less than the cost at Print-and-More.

A college parking lot is 140 ft long and 90 ft wide. The college wants to increase the area of the lot by 29% by adding strips o
Novay_Z [31]
The initial dimenssions of the park lot are:

length: 140 ft
width: 90 ft

initial area: 140 * 90 = 12,600 ft^2

Area increased 29% = 12,600 * 1.29 = 16,254 ft^2

width of the strips: x

New length: 140 + x

New width: 90 + x

New area: (140+x)(90+x) = 16,254

Solution of the equation:

12600 + 230x + x^2 = 16254

=> x^2 + 230x - 3654 = 0

Use the quadratic formula.

x = {-230 +/- √[ 230^2 - 4*1*(-3654) ]} / 2 =

x = 14.92

The other solution is negative so it is discarded.

Answer: 15 ft
