Sometimes the best way to solve an equation, a system of equations, or a system of inequalities is to look at a graph of the equation or the system. Finding solutions on graphs is different from using algebraic properties to solve for a variable, but it gives the same results. For each of the three graphs, describe how and why the graph shows the solutions of the equation or system of equations or inequalities.

answer: 5100 just subtract

step-by-step explanation:

f(x)=4

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
