the set of ordered pairs represents a function. write a rule that represents the function. (0,0), (1,7), (2,28), (3,63), (4,112) (type an expression using x as the variable) y=?

the f

last graph i believe

step-by-step explanation:

worked it out i believe

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
