hi,

So carmen has b baseball cards and she gives 12 away.= b-12

So let the cards left be x

So the expression is b-12=x.

hope it helps... :-)

The best approximation for the solution to this system of equations is (-2.2,-3)

Option C is correct.

Step-by-step explanation:

Solving the system of equations to get the exact value of x:

$y = -3\\y = x-0.8$

Let

$y = -3\,\,eq(1)\\y = x-0.8\,\,eq(2)$

Putting value of y from eq(1) into eq(2)

$-3=x-0.8$

$x=-3+0.8$

$x=-2.2$

So, Value of x is -2.2

The best approximation for the solution to this system of equations is:

x=-2.2 and y = -3

(-2.2,-3)

Option C is correct.

A system of linear equations with fewer equations than unknowns is sometimes called an underdetermined system. Can such a system

elena55 [62]

Answer:

No, it cannot have a unique solution. Because there are more variables than equations, there must be at least one free variable. If the linear system is consistent and there is at least one free variable, the solution set contains infinitely many solutions. If the linear system is inconsistent, there is no solution.

Step-by-step explanation:

the questionnaire options are incomplete, however the given option is correct

We mark this option as correct because in a linear system of equations there can be more than one solution, since the components of the equations, that is, the variables are multiple, leaving free variables which generates more alternative solutions, however when there is no consistency there will be no solution
