Mr. Brown is creating examples of systems of equations. He completes the steps to find the solution of the equation below.
beks73 [17]

Answer:

Option D.

Step-by-step explanation:

The given system of equations is

5x+2y=8    ...(1)

-4(1.25x+0.5y=2)      ...(2)

On simplifying the second equation, we get

-5x-2y=-8

On dividing by -1, we get

5x+2y=8       ...(3)

It is clear that equation (1) and (3) are same equations. It means equation (1) and (2) represent the equivalent equation.

So, the given system of equations has infinitely many solutions.

Therefore, the correct option is D.

Plssss i need help rn ​
wariber [46]

Answer:

3

Step-by-step explanation:

(x₁ , y₁) = (-1 , -2)   &    (x₂ , y₂) = (3 , 10)

Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

         = \frac{10-[-2]}{3-[-1]}\\\\=\frac{10+2}{3+1}\\\\=\frac{12}{4}\\\\=4

m  = 4

y - y₁ = m (x - x₁)

y - [-2] = 4(x - [-1])

y + 2 = 4(x + 1)

y + 2 = 4x + 4

    y = 4x + 4 - 2

    y = 4x + 2
