It’s often difficult to know which method (graphing, substitution, or linear combination) is best to use when solving a system of equations. Certain methods work much more smoothly with certain systems than others. Knowing when to use each method is a useful skill for algebra. Design a chart, flow chart, mind map, or some other visual to help you decide when to use each solution method.

< 6 cm to > 26 cm i believe

step-by-step explanation:

answer:   y=2x-3

step-by-step explanation:

there is no graph so i cant sorry

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
