The answer should be or is around 15 or 150
Y - 3x = 7 . . . . . . . . (1)
21 + 9x = 3y . . . . . .(2)
From (1), y = 3x + 7
substituting for y into (2), we have
21 + 9x = 3(3x + 7) = 9x + 21
0 = 0
Therefore, the system has an infinte number of solutions.
Answer:
d=60t
Step-by-step explanation:
Use the equation speed = distance / time
To get distance you do speed X time
D =60t shows that
Slope is rise over run which is -4/15
