Which ordered pair is a solution to the system of equations?
1 answer:
(- 2, - 3) is a solution to the given system of equations.
Answer: Option D
<u>Step-by-step explanation:</u>
Given equation are not presented in proper format. So, let assume the given system of are as below,
2 x - y = -1
2 x -4 y = 8
Now, subtract the second equation from the first, we get
(2 x - y) -(2 x - 4 y) = -1 -8
3 y = -9
y = -3 (obtained this when divide by 3)
Substituting y = - 3 into the first equation, we get
2 x - (-3) = - 1
2 x = - 1 + 3
x = - 2 (obtained when divide by 2)
Now, the answer is (x, y) = (- 2, - 3)

Answer:
a
the displacement of the plane is
b
The displacement of plane from Portland to Akron with layover at Houston is
c
the vector which defines this displacement is
Step-by-step explanation:
From the question we are the
The displacement from Portland, Oregon to Houston, Texas. is
The displacement from Houston, Texas to Akron, Ohio. is a
a
The motion of the plane in question a is in the opposite direction to vector
So the displacement of the plane is
b
The motion of Portland to Houston to Akron is in the direction of both vector and
so
The displacement of plane from Portland to Akron with layover at Houston is
c
From the question we are told that the plane flies over Portland to get to Anchorage, Alaska which implies that it is moving in opposite direction to the vector
Give that distance from Portland to Houston is
and the distance from Portland to Anchorage is km
Then the vector which defines this displacement is mathematically represented as
Answer:
The answer to the given problem is x=-11
Step-by-step explanation:
Given problem is
To solve the equation:
(multiplying the term with factor)
(adding the like terms)
(adding the like terms)
Now taking the terms to one side
(adding the like terms)
x=-11
Therefore x=-11
The answer to the given problem is x=-11
