Step-by-step explanation:
Answer:
![y](https://tex.z-dn.net/?f=y%3C4x-5)
![y\leq 2x+3](https://tex.z-dn.net/?f=y%5Cleq%202x%2B3)
Step-by-step explanation:
step 1
Find the equation of the solid line
From the graph take the points (0,3) and (4,11)
Find the slope
![m=(11-3)/(4-0)\\m=8/4=2](https://tex.z-dn.net/?f=m%3D%2811-3%29%2F%284-0%29%5C%5Cm%3D8%2F4%3D2)
The equation of the solid line in slope intercept form is equal to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
we have
![m=2](https://tex.z-dn.net/?f=m%3D2)
----> the y-intercept is the point (0,3)
substitute
![y=2x+3](https://tex.z-dn.net/?f=y%3D2x%2B3)
therefore
The inequality is
![y\leq 2x+3](https://tex.z-dn.net/?f=y%5Cleq%202x%2B3)
step 2
Find the equation of the dashed line
The slope is given
![m=4](https://tex.z-dn.net/?f=m%3D4)
From the graph take the y-intercept (0,-5)
The equation of the solid line in slope intercept form is equal to
we have
![m=4](https://tex.z-dn.net/?f=m%3D4)
substitute
![y=4x-5](https://tex.z-dn.net/?f=y%3D4x-5)
therefore
The inequality is
![y](https://tex.z-dn.net/?f=y%3C4x-5)
because the shaded region is below the dashed line
therefore
The system of inequalities is
![y](https://tex.z-dn.net/?f=y%3C4x-5)
![y\leq 2x+3](https://tex.z-dn.net/?f=y%5Cleq%202x%2B3)
I believe the equation is y=2x-1 .
hope this helps.
2x = 15 + x
First, our goal is to get 'x' to equal something by itself. To do so, we will have to do everything on one side. Let's subtract 'x' from each sides.
![2x - x = 15](https://tex.z-dn.net/?f=2x%20-%20x%20%3D%2015)
Second, our next step is to subtract '2x - x'. Since 'x' is basically considered (1), it will equal 'x'.
![x = 15](https://tex.z-dn.net/?f=x%20%3D%2015)
