Answer:
(- 3, 4)
Step-by-step explanation:
given the 2 equations
2x - y = - 10 → (1)
y = 4 → (2)
Substitute y = 4 into (1) and solve for x
2x - 4 = - 10 ( add 4 to both sides )
2x = - 6 ( divide both sides by 2 )
x = - 3
solution is (- 3, 4 )
Answer:
Step-by-step explanation:
The triangles are similar.
(x-6)/3 = x/6
x = 15
Answer:
The system is INCONSISTENT.
Equation of two parallel lines differ only by a constant.
Step-by-step explanation:
The given equations are:
2x + y = -11
6x + 3y = 15
From the graph we see that these lines are parallel. Any two parallel lines never meet. Hence, they do not have a solution.
Hence, the system is called an Inconsistent system.
Also, note that it can be seen easily from the equations are parallel without the help of a graph.
The equation 6x + 3y = 3(2x + y)
The terms (except for the constant term) are proportional. That means they represent parallel lines.
Hence, the answer.
Answer:
1.666666=1 2/3 is the amount each brother recieves.
Step-by-step explanation:
First start with dividing
5/3= 1.666666=1 2/3 is the amount each brother recieves.
We can make sure by adding 1 2/3+1 2/3+ 1 2/3=3 6/3=5
