The graph below shows a system of equations: Draw a line labeled y equals minus x plus 5 by joining the ordered pairs 0, 5 and 5

Montano1993 [528]

Answer:

The x-coordinate of the solution is x=3

Step-by-step explanation:

we have

$y=-x+5$ ------> equation A

$y=x-1$ ------> equation B

Solve the system of equations by substitution

Substitute equation B in equation A and solve for x

$x-1=-x+5$

$x+x=5+1$

$2x=6$

$x=3$

Find the value of y

$y=x-1$ ------> $y=3-1=2$

The solution of the system of equations is the point (3,2)

therefore

The x-coordinate of the solution is x=3

Mitch lives on the 20th floor of an apartment building. Every time he leaves, he rides a self-service elevator from the 20th flo

weeeeeb [17]

Answer:

He does that because he is short and his hand can't reach the 20th floor button

Step-by-step explanation:

Mitch does that simply because he is short.

When he is leaving, he doesn't need to reach the 20th floor button because the button is way taller than the reach of his hands whereas when he is returning he has to reach the 20th floor button but his hand can only reach the 15th floor button. Thus, he gets to the 15th floor and walks up the remaining 5 flights.
