Which equation has a solution of x=8.5? A −5x=42.5negative 5 x is equal to 42 point 5

B −3x=−25.5negative 3 x is equal to negative 25 point 5

C x−3.5=12x minus 3 point 5 is equal to 12

D x+2.5=−11
Pls Help!!

B

-25.5/-3=8.5

x=8.5

The correct options are : The range stays same and The domain stays same.

Explanation:

Since, given function, , where x belongs to the domain of the function and f(x) makes the range of the function.

Here, Both domain and range are the set of real number.

According to the question, when we increase a by 2 but the value of b remains same.

Then, the new function is ,

But,  the range and domain of this function is also the set of real number.

So, there is not any change in range and domain of the function.

Thus, Options first and third are correct.
