3x + 2y = 9

1 answer:

3 0

You would plug it in, so where there is a y in the first equation you will plug in the second equation, so it would become 3x+2(x-3)=9 and then solve. First you would distribute and get 3x+2x-6=9, then combine like terms and get 5x-6=9, then add 6 to both sides and get 5x=15, then divide both sides by 5 and get x=3

The answer is x=3

Which of the following statements is true?

madreJ [45]

Answer: choice 2) SAS

AB = DE is one pair of congruent sides that forms the first S in SAS. The other S in SAS refers to the pair of congruent sides BC = EF. The A in SAS is the angle pair angle B = angle E. Note how angle B and angle E are between the two pairs of congruent sides. The order of the letters matters because SAS is different from SSA, which is not a valid congruence argument.
