Ответ:
Usually systems of equations have one equation that will show the value of one variable in relation to their other, such as y=2x.
The other equation will usually show the two variables in relationship to another number, such as x+y=15.
To make a system of equations for this point, we need to show one variable’s value in relation to the other. We could put that x=2/3y.
Now we show x and y in relation to another number. We could put that x+y=-5.
Note that we could add y intercepts and extra coefficients to these equations, but for now I am keeping it simple.
Now we have a possible system of equations.
x=2/3y
x+y=-5
When solving for the values of x and y, you could substitute the first equation for x in the second equation to solve.
I hope this helps!
Ответ:
the answer is y=(x-5)^2-1 (this is a two square)
