To do these problems, plug in a couple of values into the equations, and see the general shape of the graph. To ensure you were right, check them on an online graphing calculator. I highly recommend Desmos Graphing Calculator. Cheers!
Answer:

Step-by-step explanation:
2 workers, each 8 per hour, for 40hrs a week, so one earns 8 * 40, or 320 bucks, is two workers, so 320 + 320 or 640 bucks
if 2000 is the 100%, how much is 640 in percentage off of it?
well
solve for "x"
The answer to that is 58,805,595 . hope this helps !!!
Answer:
The ordered pair (4,1) gives a true statement for both equations.
Step-by-step explanation:
So for the first equation, x + 2y = 6. The ordered pair is (4,1). This means x=4 and y=1 because ordered pairs are in (x,y) form. First substitute the x and y values into the first equation
Let x=4 y=1
x + 2y = 6.
4 + 2(1) = 6
4 + 2 = 6
6=6. This means that the ordered pair works for the first equation.
Now, the second equation. x - y = 3.
Again, substitute the x and y values.
4 - 1 = 3
3=3. This means that the ordered pair (4,1) works for the second equation.
The ordered pair (4,1) gives a true statement for both equations.
