Mathematics
1 answer:
frosja888 [35]3 years ago
5 0

Answer:

Step-by-step explanation:

18). 3x + 2 ÷ 3x = \frac{2}{3x}

     Since, 3x + 2 ÷ 3x = 3x + \frac{2}{3x}

      Therefore, right hand side of the equation will be = 3x + \frac{2}{3x}

20). \frac{4x+3}{3}=x+1

       Since, \frac{4x+3}{3}=\frac{4x}{3}+\frac{3}{3}

                            = \frac{4}{3}x+1

Therefore, right hand side of the equation should be \frac{4}{3}x+1.

Which graph represents the solution set to this system of equations? –x + 2y = 6 and 4x + y = 3 On a coordinate plane, a line go
erastova [34]

Answer:

On a coordinate plane, a line goes through (0, 3) and (2, 4) and another line goes through (0, 3) and (0.75, 0).

This answer almost coincide with option C. I suppose there was a mistype.

Step-by-step explanation:

The system of equations is formed by:

–x + 2y = 6

4x + y = 3

In the picture attached, the solution set is shown.

The first equation goes through (0, 3) and (2, 4), as can be checked by:

–(0) + 2(3) = 6

–(2) + 2(4) = 6

The second goes through (0, 3) and (0.75, 0), as can be checked by:

4(0) + (3) = 3

4(0.75) + (0) = 3
