Answer: The correct option is (D) 36.
Step-by-step explanation: We are given to find the value of 'y' that would make OP parallel to LN.
MO = 28 units, OL= 14 units, Pl = 18 units and MP = y = ?
From the figure, we have
if OP ║ LN, then we must have
∠MOP = ∠MLN
and
∠MPO = ∠MNL.
Since ∠M is common to both the triangles MOP and MLN, so by AAA postulate, we get
ΔMOP similar to ΔMLN.
We know that the corresponding sides of two similar triangles are proportional, so
![\dfrac{MO}{ML}=\dfrac{MP}{MN}\\\\\\\Rightarrow \dfrac{MO}{MO+OL}=\dfrac{MP}{MP+PN}\\\\\\\Rightarrow \dfrac{28}{28+14}=\dfrac{y}{y+18}\\\\\\\Rightarrow \dfrac{28}{42}=\dfrac{y}{y+18}\\\\\\\Rightarrow \dfrac{2}{3}=\dfrac{y}{y+18}\\\\\\\Rightarrow 2y+36=3y\\\\\Rightarrow y=36.](https://tex.z-dn.net/?f=%5Cdfrac%7BMO%7D%7BML%7D%3D%5Cdfrac%7BMP%7D%7BMN%7D%5C%5C%5C%5C%5C%5C%5CRightarrow%20%5Cdfrac%7BMO%7D%7BMO%2BOL%7D%3D%5Cdfrac%7BMP%7D%7BMP%2BPN%7D%5C%5C%5C%5C%5C%5C%5CRightarrow%20%5Cdfrac%7B28%7D%7B28%2B14%7D%3D%5Cdfrac%7By%7D%7By%2B18%7D%5C%5C%5C%5C%5C%5C%5CRightarrow%20%5Cdfrac%7B28%7D%7B42%7D%3D%5Cdfrac%7By%7D%7By%2B18%7D%5C%5C%5C%5C%5C%5C%5CRightarrow%20%5Cdfrac%7B2%7D%7B3%7D%3D%5Cdfrac%7By%7D%7By%2B18%7D%5C%5C%5C%5C%5C%5C%5CRightarrow%202y%2B36%3D3y%5C%5C%5C%5C%5CRightarrow%20y%3D36.)
Thus, the required value of 'y' is 36.
(D) is the correct option.
c. Infinitely many solutions is the right answer
Step-by-step explanation:
Given equations are:
![x + 6y = -6\ \ \ \ Eqn\ 1\\2x + 12y = -12\ \ \ Eqn\ 2](https://tex.z-dn.net/?f=x%20%2B%206y%20%3D%20-6%5C%20%5C%20%5C%20%5C%20Eqn%5C%201%5C%5C2x%20%2B%2012y%20%3D%20-12%5C%20%5C%20%5C%20Eqn%5C%202)
When we closely observe the equations we see that both the equations are equivalent.
From equation 2:
Dividing the equation by 2
![x+6y = -6](https://tex.z-dn.net/?f=x%2B6y%20%3D%20-6)
We can see that the equation 2 is equivalent to equation 1.
This means that the graph of both equations will be on each other so the equations will have infinite many solutions
Hence,
c. Infinitely many solutions is the right answer
