Standard form of a linear equation -2x+3=4y

The perimeter of a movie screen is 54 meters. the screen is 18 meters wide. how tall is it?

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

What are the domain and range of the function f(x)=2^x+1
