Answer: y=x+5/2
Step-by-step explanation:
using the slope intercept formula, y=mx+b where m is the slope and b is the y-intercept, you can substitute the two values to get y=x+5/2. Please note that the slope, m, is one so it's not shown.
(11x+10)(x+-1)
(X+1)(11x+-10)
Answer:

Step-by-step explanation:
we have

where
t is the time in seconds
h is the dolphin's height in feet
we know that
When the dolphin return to the water the value of h(t) is equal to zero
so
For h(t)=0


Simplify
