There are infinitely many solutions.

Explanation:

The equation is -\frac{1}{2} x+\frac{1}{2}y=-1 and x-y=2

Now, we shall solve the equation by substitution method.

Let us substitute x=y+2 in -\frac{1}{2} x+\frac{1}{2}y=-1

-\frac{1}{2}(y+2)+\frac{1}{2} y=-1

Multiplying the terms within the bracket,

-\frac{1}{2} y-1+\frac{1}{2} y=-1

Adding both sides by 1, we get,

-\frac{1}{2} y+\frac{1}{2} y=0

Adding both sides by \frac{1}{2} y,

\frac{1}{2} y=\frac{1}{2} y

Since, both sides of the equation are equal, the system of equations have infinitely many solutions.

Answer:

See attachment :D

Step-by-step explanation:

y = 2/3x + 2

This is in slope-intercept form, y = mx+b. m is the slope, 2/3, and b is the y- intercept, 2. So you know the line intersects with the y-axis at (0,2). The slope is 2/3. So you can move up two points, then over three. Because it's a positive slope, you move right. This leaves you at point (0,3). Connect a line between these two points.

The line intersects with points (-3,0) and (0,2).

Hope this is helpful ^^ Good luck with your test :D

What is the measure of PQR
allsm [11]
I believe it’s 86
Since it tells you the measurements of two arcs that are opposite of one another you just add them together and divide it by two since the arcs correspond with the angle you’re looking for 86 is your answer
