Graph the system of equations.<br><br> {2x - y =4<br> {x - y = -2
Mnenie [13.5K]

Answer:

See attachment

Step-by-step explanation:

The given system is

2x-y=4

x-y=-2

We write the system in slope-intercept form:

y=2x-4

y=x+2

The first equation has slope of 2 and y-intercept at (0,-4)

When y=0, x=2.

We plot (0,-4) and (2,0) to graph this first equation.

The second equation has a slope of 1 and a y-intercept at (0,2)

Also when y=0, x=-2.

We plot (0,2) and (-2,0) and draw a straight line through them.

The graph of the system is shown in the attachment.

Please help it is 10th grade Equations of lines and circles 7. Michael is hanging out in the park and needs to keep his so
frosja888 [35]

Step-by-step explanation:

1) the required equation in common form is:

(x-x₀)²+(y-y₀)²=r², where (x₀;y₀) - coordinates, where Michael is standing; r - the social distance;

According to the common form and given coordinates (x₀=-5; y₀=2; r=6) it is possible to make up the required equation:

<u>(x+5)²+(y-2)²=6².</u>

2) if the distance between two friends is:

d=\sqrt{(-5-1)^2+(2-1)^2}=\sqrt{37}, \ then

this distance is longer than social (6 ft). For more info see the attachment.
