Answer:
Step-by-step explanation:
If BOTH equations are in slope-intercept form then the-graphing-? method would be best, but the-substitution-? method would also be effective since both y's are already by itself.
If ONE of the equations is solved for x or y and the other equation is not, then the-substitution-? method is best.
If BOTH equations are lined up in standard form & the coefficients of x or y are opposites then the BEST method is definitely the-elimination--? method.
If BOTH equations are lined up in standard form the elimination method would be best. But if the coefficient of x or y is 1, then the-substitution--? method is also effective.
Answer:
D
Step-by-step explanation:
This is because they are both mulitplied by two so they are still equivalent
The answer is 3, since 3*3*3 equals 27
4.3
5 or more raise the score
4 or less let it rest
