Correct option is C)
On putting x=2y+5 in second equation, we get
y=(4y+7)(2y+14)
⇒8y 2 +70y+98=y
⇒8y 2+69y+98=0
Discriminant D=69 2−4(8)(98)=1625>0
Hence, the equation has 2 real roots.
Therefore, there are 2 ordered pair.
Option C is correct.

I Hope my Answer help you

We are considering the function 
the graph of this function is the graph of the parent function
after applying the following steps.
1. multiply by -1:
is 
reflected with respect to the x-axis.
2. multiply by 5:
is shrinked towards the y axis.
for example, consider x=1/2
now this means that is "lower" than , which means there is a shrinking of the graph.
3. add 5:
is 
shifted 5 units up.
4.
so the graph of the function a) opens down, b) is shifted 5 units up, c) is not wider than the parent function
Answer: False
