Answer: y=8
Step-by-step explanation:
Answer:
(2,2)
Step-by-step explanation:
Diameter of the larger gear х см
1/4х = 16 - 2.5
1/4x = 13.5
x = 13.5 * 4
x = 54 cm - diameter of the larger gear /
Since anything within absolute value signs is ≥0, we know that the minimum value, when x=-2, is 7
So the vertex is the point (-2, 7)
