-5.6(repeating 6), -√(21), 3&9/10, 5.2
There are 98 terms.
98*(33+130)/2 = 7987
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.
