Answer:
r = t(r-3)
Step-by-step explanation:
t = r/r-3
r/r-3 = t
r = t x (r-3)
Answer:
miles per minute represents the speed of the bird and 3 miles represents the original distance of the bird from its nest.
Step-by-step explanation:
As there is no graph mentioned here but the information are quite sufficient to answer the question.
We have points
From these points we can find the slope of the line .
From point slope formula
And assigning and
This slope is also the speed of the bird which is
As by plugging the values of any coordinate point we can confirm this.
Lets put , y-axis is the distance so in minutes the the distance covered by the bird must be equal to to y-axis value which is miles.
Now as in the bird has started from y-intercept value so we can say that,the original distance of the bird from its nest is .
So the correct choices are: and
The birds speed is per minute and is away from its nest.

Answer:
The angle complies with the state regulations.
Step-by-step explanation:
The angle of elevation is the angle in the figure, and from trigonometry we find that
taking the inverse sine of both sides we get
which gives
which is less than 5°, and therefore is well within the state regulations.
Answer:
(1;-2)
Step-by-step explanation:
x=-2y-3
2(2y+3)=-6y-9-5
10y=-20
y=-2
x=4-3=1
