Answer:
There should be 3 points that you have. (0, 3), (2, 6), and (-2, 0)
Step-by-step explanation:
Alright so since everything there is divisible by 9 you can divide each number by 9 to get:
-3x + 2y = 6
Now, to graph this you need to put it in y = mx + b form. So, add the 3x to both sides of the equation.
-3x +2y = 6
+3x +3x
2y = 3x + 6
Now you would divide 2 on both sides because you need y to be alone, to get:
y = 3/2 x + 3
Now Graphing:
Since 3 is positive that is your y-axis. So put a dot on + 3 on the y-axis. That's your (0, 3) point.
Then 3/2 is your slope. Slope is rise / run. So you start at your dot from the y-axis go up 3 (because that's your rise from slope) then you go to the right 2 (therefore, your run) then place a dot there. This is your (2, 6) point)
Usually you want to do the negative side of that also. To do that you would once again start at the 3 (y-axis point). Now you would pretty much make your slope negative. Starting at 3, you would go down 3 (your rise for slope) then go to the left 2 (your run for slope). This is your (-2, 0) point.
Do you understand it?
Answer:
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>let's solve:</h3>
A and b are the minutes spent on machine A and machine B, respectively.
a+b = 40
b = 40-a
8a + 6b = 300
8a + 6(40-a) = 300
8a + 240 - 6a = 300
2a = 60
a = 30
b = 40-a = 10
30 minutes on machine A and 10 minutes on machine B
