If RS = 5x + 2, ST = 7x − 12, and RT = 11x + 6, what is ST?
Sergeeva-Olga [200]

Answer:

ST = 100

Step-by-step explanation:

RS + ST = RT

(5x +2) + (7x -12) = 11x + 6

5x + 7x - 11x    = 6 - 2 + 12

                   x = 16

ST = 7x - 12 = 7*16 - 12 =  112 - 12

ST = 100

a line passes through (3, 7) and (6, 9). which equation best represents the line? y = 3/2 x 5 y = 2/3 x 5 y = 3x 2 y = 2/3 x 2
allochka39001 [22]
Given two points, the equation of the line may be determined by,
                            y - y1 = ((y2 - y1) / (x2 - x1))(x - x1)
Substituting the given values,
                                y - 7 = ((9 - 7) / (6 - 3))(x - 3)
Simplification will yield to an answer of,
                                     y = 2x/3 +5
Thus, the answer is the second choice.
