7 0

Answer:

yes, no, and no

Step-by-step explanation:

What you do is you just plug what is in the parenthesis into the equation. So you have 2x+5y=19. You will take the (7, 1) and plug the 7 into the x and the 1 into the y to get 2(7)+5(1)=19. 14+5=19. 19=19.

Find the distance between the points given. (0,5) and (-5,0)
galina1969 [7]

Answer:

5\sqrt{2}

Step-by-step explanation:

Calculate the distance between the points using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (- 5, 0)

d = \sqrt{(-5-0)^2+(0-5)^2}

  = \sqrt{(-5)^2+(-5)^2}

  = \sqrt{25+25} = \sqrt{50} = 5\sqrt{2} ← exact value
