The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations?

(9, 3)  

Step-by-step explanation:

(1) 4(0.25x + 0.5 y) = 3.75 ⟶ x + 2y = 15

(2)                 4x - 8y = 12 ⟶ x  -  2y =   3

                                                    2x = 18

                                                       x = 9

                                               9 - 2y = 3

                                                   -2y = -6

                                                      y = 3

The solution of the system of equations is (9, 3).

The graph of Equation (1) (blue) intersects that of Equation (2) (red) at (9, 3).

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
