Answer:
For [tex]y=0.1[/tex] the value is a prime number.
Step-by-step explanation:
Given:
[tex]y=0.4[/tex]
[tex]10y + 2[/tex] is an even number.
We need to find the value of y for which value of equation is prime number.
Solution:
Let us assume that [tex]y=0.1[/tex]
Substituting the value in given equation we get;
[tex]10y+2\\\\=10\times 0.1+2\\\\=1+2\\\\=3[/tex]
Which is a prime number.
Hence We can say that for [tex]y=0.1[/tex] the value is a prime number.
