miskamm [114]2 years ago
8 0

Step-by-step explanation:

Let x be the son's age. The father's age is 3x and 3x - x = 24.

Therefore 2x = 24 and x = 12.

The son's age is 12 and the father's age is 36 at present.

-3x-7y=37 which ordered pair is a solution to this equation
docker41 [41]
In this item, we are not given with the choices for the ordered pair which could be the solution to the given equation. What can be done is to assume a value for one of the variables and solve for the other. To be able to find one that satisfies let x be equal to zero and substitute to the given equation.

    -3(0) - 7y = 37

Simplifying,
  
    -0 - 7y = 37

The value of y from the equation is 37/7. Thus, one of the ordered pairs that satisfies the equation is,

   (0, 37/7)

A line passes through the points (-1,-1) and (5,8) which points lie on the same line?
djverab [1.8K]

Answer: all points (x,y) that satisfy y=\frac{3}{2}x+\frac{1}{2}

Step-by-step explanation:

The slope of the line is

\frac{-1-8}{-1-5}=\frac{-9}{-6}=\frac{3}{2}

So, substituting into point-slope form, the equation is

y+1=\frac{3}{2}(x+1)\\\\y+1=\frac{3}{2}x+\frac{3}{2}\\\\y=\frac{3}{2}x+\frac{1}{2}

Therefore, all points (x,y) that satisfy y=\frac{3}{2}x+\frac{1}{2} will lie on the same line.
