The ordered pair (1, -2) is a solution to the system of linear equations.

Mathematics
1 answer:
vesna_86 [32]3 years ago
3 0

Answer:

False

Step-by-step explanation:

2x + y = 0

Try (1, -2)

2(1) + (-2) = 0

2 + (-2) = 0

0 = 0

The solution works on the first equation.

-x + 2y = 5

-(1) + 2(-2) = 5

-1 - 4 = 5

-5 = 5

The solution does not work in the second equation.

Answer: False

a rectangular parking lot has a lenth that is 6 yard graeter than the width the area of the parking lot is 160 ssquar yardsd. fi
Lubov Fominskaja [6]

Answer:

<h3><u>Required Answer</u><u>:</u><u>-</u></h3>

Let

the breadth =x

the length =6x

  • \sf Area=160yard^2

As we know that in a rectangle

{\boxed{\sf Area=lb}}

  • Substitute the values

{:}\longrightarrow\sf x\times 6x=160

{:}\longrightarrow\sf 6x^2=160

{:}\longrightarrow\sf x^2={\dfrac {160}{6}}

{:}\longrightarrow\sf x^2=26.6

{:}\longrightarrow\sf x=\sqrt {26.6}

{:}\longrightarrow\sf x=5.1yards

  • Length=6\times 5.1=30.6yards
  • Breadth=5.1yards

The midpoint of AB = ([?], [])<br> M = (x¹+x², ¹2²)<br> PLS HELP I WILL MARK BRAINLIEST
OlgaM077 [116]

Answer:

\sf M=\left(-\dfrac{1}{2},0\right)

Step-by-step explanation:

Let (x₁, y₁) = Point A = (-2, 1)

Let (x₂, y₂) = Point B = (1, -1)

\sf Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)

\implies \sf Midpoint=\left(\dfrac{-2+1}{2},\dfrac{1+(-1)}{2}\right)

\implies \sf Midpoint=\left(-\dfrac{1}{2},0\right)

The terminal ray of angle β , drawn in standard position, passes through the point (−5, 2√7) . What is the value of cos β ? Ente
Alexxx [7]

Step-by-step explanation:

Draw the triangle formed by the ray.

The hypotenuse of the triangle is:

c² = a² + b²

c² = (-5)² + (2√7)²

c² = 25 + 28

c = √53

Therefore:

cos β = -5 / √53

Or, as a proper fraction:

cos β = -5√53 / 53
