Use < , > , = , ≤ , ≥ to complete these statements. 1) if x < y , then y___ x, 2) if x > 5 and 5 > y, then x ___
vodomira [7]

Answer:

1) y > x

2) x > 5 > y

3) x ≤ 4  ( or 4 ≥ x )

4) x = y

Step-by-step explanation:

1) 1. y is greater than x

  2. so y > x

2) 1. 5 is less than x and more than y

   2. we can write this like x > 5 > y

   3. you can just squish them together as a shortcut usually: x > 5 and 5 > y      -->      x > 5 > y

3) 1. x is for at most, we can say this as x is less than or equal to 4

   2. this is written as x ≤ 4  or  4 ≥ x

4) 1. x - y = 0 so x and y must be the same value

   2. therefore x = y

Write an equation for the perpendicular bisector of the line segment joining the two points.
Leona [35]
Points (1, 7)  and  (-3, 2)

Slope for a line between (x₁, y₁) and (x₂, y₂) , m = (y₂ -y₁) / (x₂- x₁)

The slope for the line joining the two points =  (2 - 7) / (-3 - 1) = -5/-4

Slope = 5/4

Hence the perpendicular bisector would have a slope of -1/(5/4) = -4/5

By condition of perpendicularity

For points (1, 7)  and  (-3, 2),

Formula for midpoints for (x₁, y₁) and (x₂, y₂) is ((x₁ +x₂)/2 , (y₁+ y₂)/2)

Midpoint for (1, 7)  and  (-3, 2) = ((1+ -3)/2 , (7+2)/2) = (-2/2, 9/2)

= (-1, 9/2)

Since the slope of perpendicular bisector is -4/5 and passes through the midpoint (-1, 9/2)

Equation  y - y₁ = m (x - x₁)

                y - 9/2 = (-4/5) (x - -1)
           
                y - 9/2 = (-4/5)(x + 1)

               5(y - 9/2) = -4(x + 1)

               5y - 45/2 = -4x - 4

                 5y =  -4x - 4 + 45/2
           
                5y + 4x = 45/2 - 4

                  5y + 4x = 22  1/2  - 4 =  18 1/2

                  5y + 4x =  37/2

                  10y + 8x = 37

The equation of the line to perpendicular bisector is 10y + 8x = 37
