Answer:

if an equation has the same slope and y intercept the equations will have infinite many solutions. If both equations have the same slope but different y intercept the equations will have no solutions. if both equations are positive or negative and have different slopes and different y intercepts then they will most likely have one solution. (example: y=-2x+3 and y= -4x+4, both slopes are negative so there will be one solution, same goes for if both slopes are positive.

Hope this helps!

Can someone please calculate the length ?
masya89 [10]
<h3>Answer:  11/20</h3>

=====================================================

Work Shown:

x = unknown horizontal length

1/5 = 0.2

Perimeter = 2*(width + length)

P = 2*(0.2 + x)

P = 0.4 + 2x

Set this equal to the given perimeter of 1 & 1/2 = 1.5 and solve for x

0.4 + 2x = 1.5

2x = 1.5-0.4

2x = 1.1

x = (1.1)/2

x = 0.55

x = 55/100

x = (5*11)/(5*20)

x = 11/20
