8m+27= 2m-3
take 2m and subtract it from 8m, this gives you 6m. now your equation is 6m+27=-3.
subtract 27 from -3, this will make it 6m=-30.
divide 30 by 6. this gives you your answer. m=-5, because -30 divided by 6 equals -5.
now to test it you can plug -5 into the equation in place of M. 8 times -5 equals -40, plus 27 equals -13. 2 times -5 equals -10 plus -3 equals -13.

Which of the lines below is parallel to a line with a slope of 3 and a y-intercept at (0, 3)?

Dmitrij [34]

Answer:

$\displaystyle line\:HJ$

Step-by-step explanation:

$\displaystyle y = 3x + 3$

The descryption gives you the above Slope-Intercept Equation. Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], therefore $\displaystyle 3$ remains as is, and perfourming $\displaystyle \frac{rise}{run},$ will give you that answer.
