The first option, because if it’s 291 yards and 1/4 BELOW (below: meaning negative because you are under the usual sea level).
-291 (1/4)
Hope this helped!
Answer:
u = ± 4
Step-by-step explanation:
Given
u² = 16 ( take the square root of both sides )
u = ± 
= ± 4
u = - 4, u = 4

Answer:</h3>
C) y = 6x
<h3>
Step-by-step explanation:</h3>
Pick any point. It is often convenient to use x = 1 (no marked point) or x = 10 (where y = 60).
Use these values to see which equation agrees.
A: 60 ≠ (1/6)·10
B: 60 ≠ 2·20
C: 60 = 6·10
D: 60 ≠ 12·10
____
Or, you can solve ...
... y = kx
for k, using the point values you found on the graph.
... 60 = k·10
... 60/10 = k = 6 . . . . . divide by 10
This makes the equation be ...
... y = 6x . . . . . . matches selection C
She walks 6/5 of a mile in 1 hour
So, she walks 1.2 miles per hour
