To find the value of y in the expression 15y-4 = 41, you need to isolate y. Start by adding 4 to both sides of the equation to get 15y = 45. Then, divide both sides by 15 to solve for y, which equals 3. Therefore, the value of y in the expression 15y-4 when it equals 41 is 3.
It would help if the expression was given!
Depends what the expression is. Just plug in 8 for y in the expression and that'll do it for you.
Yes.
you test it by giving the letters a value say if X equals 5 and Y equals 7 then you calculate both expressions with that value. If both answers are the same, then the simplified expression is correct, or an equivalent.
The value is 1 if (x, y) = (4, 3) and 0 otherwise.

You don't, unless you know either the value of x or what the expression equals.
The answer is -369.
To evaluate the expression when ( n ) equals a specific value, you substitute that value into the expression in place of ( n ). For example, if the expression is ( f(n) = n^2 + 3n ), you would calculate ( f(7) ) by substituting 7 for ( n ), resulting in ( 7^2 + 3(7) ). Similarly, for ( n = 0.4 ), you would substitute 0.4 into the expression and compute the result. This process allows you to find the numerical value of the expression for those specific values of ( n ).
