Answer:
- y < -2x +3
- y > 1/2x -2
Step-by-step explanation:
To find the equation of each boundary line, look for the y-intercept. Then find the rise and run to the next grid intersection to the right that is crossed by that line. The equation for the line is ...
y = mx + b . . . . . . m = rise/run = slope; b = y-intercept.

The lines are both dashed, so the inequalities will not include the "or equal to" case. For line (1), the shading is below the line, so the appropriate inequality symbol is <. For line (2), the shading is above the line, so the appropriate inequality symbol is >.
__
<u>Line 1</u>
y-intercept = +3. m = -2/1 = -2
y < -2x +3
<u>Line 2</u>
y-intercept = -2. m = 1/2
y > 1/2x -2
Answer:
linear with a common first difference of 2
Step-by-step explanation:
If this is linear, the common first difference, or slope, will be the same throughout the entire table.
The formula for slope is

For the first set of points, we have:
m=(0--2)/(-2--3) = (0+2)/(-2+3) = 2/1 = 2
For the second set of points, we have:
m = (4-0)/(0--2) = 4/(0+2) = 4/2 = 2
For the third set of points, we have:
m = (12-4)/(4-0) = 8/4 = 2
The rate of change, or slope, is constant; this makes the function a linear function with a common first difference of 2
Hope it helps
Answer: (1,-1)
Step-by-step explanation:
- You can multiply the first equation by -1
- Add the equations.
- Solve for x, as following:
- Substitute the value of x into any of the original equations and then you must solve for y:
Therefore, the solution is: (1,-1)
It’s depends on your grade level if yiu in high school it totally different
V=10. You can solve this by using the rule of subtracting negative numbers, which means if you are subtracting a negative it is the same as adding a positive. So basically V + 9 = 19, making V equal 10.
