What are the classifications of each system?
column b name each number
a. consistent independent
b. coincident
c. inconsistent
column a
1. x+5x=-2
x+5y=4
2. y=3x+4
-2x+y=4
3. y= -x+3
2x+2y=6
4. 5x+2y=-4
5x-2y=3
plz ive been stuck on this for like 2 hours now! : (

X + 5x = -2
      6x = -2
       6      6
        x = ⁻¹/₃

    x + 5y = 4
  ⁻¹/₃ + 5y = 4
+ ¹/₃        + ¹/₃
          5y = 4¹/₃
           5      5
            y = ¹³/₁₅
      (x, y) = (⁻¹/₃, ¹³/₁₅)
It is consistent and independent.

y = 3x + 4
-2x + y = 4

        -2x + y = 4
-2x + 3x + 4 = 4
           x + 4 = 4
               - 4  - 4
                 x = 0
y = 3x + 4
y = 3(0) + 4
y = 0 + 4
y = 4
(x, y) = (0, 4)
It is consistent and independent.

y = -x + 3
2x + 2y = 6

             2x + 2y = 6
    2x + 2(-x + 3) = 6
2x + 2(-x) + 2(3) = 6
         2x - 2x + 6 = 6
                        6 = 6
It is consistent and dependent.

5x + 2y = -4
 5x - 2y = 3
      10x = -1
       10    10 
          x = ⁻¹/₁₀

     5x + 2y = -4
5(⁻¹/₁₀) + 2y = -4
      ⁻¹/₂ + 2y = -4
     + ¹/₂         + ¹/₂
              2y = -3¹/₂
               2       2
                y = -1³/₄
          (x, y) = (⁻¹/₁₀, -1³/₄)
It is consistent and independent.

60 ÷ -20 x makes x = -3

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
