Answer:
That's strange. (-1/2, 5) would work for both if only the top equation had a less than or equal to sign. If all else fails, just puts c as your answer lol
Step-by-step explanation:
Answer:
about 11
Step-by-step explanation:
Thats means angle BEC is 63. By the vertical angle theorem AED is the same. 3x-27 when x=30 is also 63.
Given:
The graph of system of inequalities.
To find:
The inequalities.
Solution:
From the given graph it is clear that dotted line is a vertical line parallel to the x-axis and one unit above the x-axis. So, the equation of dotted line is
The area below the dotted line is shaded. It means, y values must be less than 1. So, the required inequality for dotted line is
...(i)
Solid line passes through (-5,-5), (0,0) and (5,5). It means y is directly proportional to x with 1 as constant of proportionality. So, the equation of solid line is
The area above the solid line is shaded. It means, y values must be greater than or equal to x. So, the required inequality for solid line is
...(ii)
So, the system of inequalities have inequalities and .
Therefore, the correct option is D.
Answer:
n=0
Step-by-step explanation:
Clear parenthesis w/ distribution:
3(-7n+1)=-21n+3
Move everything over to one side:
6n+3=-21n+3
6n=21n Subtract the 3 on the right.
-15n=0 Subtract the 21.
n=0 Divide the -15.
