Is 4(y+3) equivalent to 4y +3?

no

Step-by-step explanation:

because 4(y+3)= 4x3y=12y

and 4y+3=7

(im not sure if thats why or not but i think i know its not equivalent)

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
