Answer:
No solutions
Step-by-step explanation:
i did this via substitution so i hope it isn't a problem
3x+y=4
6x+2y=−4
Step: Solve 3x+y=4for y:
3x+y+−3x=4+−3x(Add -3x to both sides)
y=−3x+4
Step: Substitute−3x+4foryin6x+2y=−4:
6x+2y=−4
6x+2(−3x+4)=−4
8=−4(Simplify both sides of the equation)
8+−8=−4+−8(Add -8 to both sides)
0=−12
so there are no solutions
hope this helps!!
The plot of land forms right triangle.
Step-by-step explanation:
Let,
the three sides are a,b and c.
The sum of square of two sides equals to the square of third side. We will consider the larger side as c, therefore,
a= 2000 feet
b= 2100 feet
c= 2900 feet
Using Pythagoras theorem;
As the three sides satisfy pythagoras theorem, therefore, the plot of land form right triangle.
The plot of land forms right triangle.

Yes. A pentagon is any closed polygon with five sides.
Answer:
102
Step-by-step explanation:
You have to substitute x and y. Since x = 3 and y = 4, you would write the equation as 6(3) + 21(4). Multiply that, and you get 18 + 84. Add that together, and you get the answer 102.
We know that
in a triangle ABC
a) the line AB is is included between <span>line BC and line AC
b) </span>the line BC is is included between line AB and line AC
c) the line AC is is included between line AB and line BC
therefore
the answer is
the line AB is is included between line BC and line AC
