Answer:
For part one 30000 and the slope for part two is -2000 and for part three it is y=30000=2000x.
Step-by-step explanation:
If it starts at 30,000 then that is on the 0 on the x-axis.
While the plane is descending by 2000 so that is the slope but because it is descending and not rising it is -2000. If it was rising it would be 2000.
And for part three because it starts and 30000 and it goes down 2000 by the x-axis.
Hope this helps.
Janet = 1/3
Gary = 1/2
(1/3) + (1/2) = 5/6
Let x = time they both can do the job together
(1/2) + (5/6)x = 1
Solve for x to find your answer.
The equation of the line in point-slope form is given by:

Where,
(xo, yo): point that belongs to the line
m: slope of the line
The slope is given by:

Substituting values:

Rewriting:

Now we choose an ordered pair:

Substituting values we have:

We now rewrite the equation in its standard form:

Where,
b: cut with the y axis.
We have then:
Answer: point-slope form: 
or
standard form
Answer:
a=7.85-1/2^b
Step-by-step explanation:
2a=15.7-b Move variable to the right side and change its sign
2a=15.7-b Divide both sides of the equation by 2
a=7.85-1/2^b The final solution for a is
