Ineed quick with two math questions, 98 points. graph the system of equations on your graph paper to answer the question. {y=x+2 y=−x+8 {3x−8y=29 3x+y=−2 which ordered pair is the best estimate for the solution to the system? (0.5, −3.5) (0.75, −2.25) (0, −3.75) (0, −2) what is the solution for this system of equations?

He mass of a single atom of carbon can be found by dividing the atomic mass (12.01 g) by 6.022 x 10^23. which is the mass of a single carbon atom, correctly written in scientific notation with the correct number of significant figures?

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
