Answer:
AB = CD
BC = DA
Step-by-step explanation:
Since 3x+2 = 5x-2, solving for x yields 2. Since BC = 4x+1 = DA, BC and DA both equal 4(2)+1 = 9.
Answer:
The question is missing, so I will answer all the solution for each possible system of two equations.
Step-by-step explanation:
The equations
x + 5 y = 10 (red)
3 x - y = 1 (blue)
x - 5 y = 10 (green)
3 x + y = 1 (purple)
are shown in the picture atatched. The intersection between two lines is the solution of their system.
<u>system:</u>
x + 5 y = 10 (red)
3 x - y = 1 (blue)
<u>solution</u>: (0.938, 1.813)
<u>system</u>:
x + 5 y = 10 (red)
x - 5 y = 10 (green)
<u>solution</u>: (10, 0)
<u>system</u>:
x + 5 y = 10 (red)
3 x + y = 1 (purple)
<u>solution</u>: (-0.357, 2.071)
<u>system</u>:
3 x - y = 1 (blue)
x - 5 y = 10 (green)
<u>solution</u>: (-0.357, -2.071)
<u>system</u>:
3 x - y = 1 (blue)
3 x + y = 1 (purple)
<u>solution</u>: (0.333, 0)
<u>system</u>:
x - 5 y = 10 (green)
3 x + y = 1 (purple)
<u>solution</u>: (0.938, -1.813)
Answer:
0,0215
Step-by-step explanation:
w = 
collect the term in w together → ( subtract 2w from both sides)
y - aw - 2w = - 1 → ( subtract y from both sides)
- aw - 2w = - 1 - y → ( multiply through by (- 1) )
aw + 2w = 1 + y → ( take out w as a common factor )
w( a + 2)= 1 + y → ( divide both sides by (a + 2 ) )
w =
