Which of the following terms best describes a group of equations in which at least one equation is nonlinear, all of the equations have the same variables, and all of the equations are used together to solve a problem? a. system of linear inequalities b. system of linear equations c. system of nonlinear equations d. system of nonlinear inequalities

C. System of non-linear equations

Explanation:
A system is defined as a group of equations/inequalities all having the same variables and are solved together.

Since we are looking for a system of EQUATIONS, we can exclude options A and D since they refer to inequalities

Now, we are left with options B and C:
1- Option B:
This options refers to a system of linear equations. This means that all equations in the system are linear. Therefore, this option is incorrect

2- Option C:
This option refers to a system of non-linear equations. This means that at least one of the equations in the systems is non-linear. This fits the description given in the question. Therefore, this is the correct option

Hope this helps :)

Iwish i knew the answer but i don’t but someone will come and us
