Answer:
x>-2
Step-by-step explanation:
(30 1/2) / (3 3/4) =
(61/2) / (15/4) =
61/2 * 4/15 =
122/15 =
8 2/15 hot dogs were eaten in 1 minute <==
It's B
Slope is negative, the other must be positive due to m1 x m2 = - 1
m1 = -2/5
The diagram shows a gradient of -2/5. So, the
reciprocal of this valve to make - 1 is 5/2 (which is the - 2/5 flipped upside down, but positive)
-2/5 x 5/2 = - 10/10 (or - 1)
Thus, the perpendicular line to this has a gradient of 5/2.
