Answer:
Undefined
Step-by-step explanation:
Use rise over run (y2 - y1) / (x2 - x1), where (x1, y1) and (y1, y2) are points on the line
Plug in the given points:
(y2 - y1) / (x2 - x1)
(-8 - 7) / (3 - 3)
-15/0
= undefined
The slope is undefined, because you cannot divide by 0.
Answer:
B. -90
Step-by-step explanation:
a1=9; d=-3
a34=9-3(33-1)=-90
Let's assume
height of plane in feet =h
time in minutes =t
we are given
A plane is descending into the airport. After 5 minutes it is at a height of 6500 feet
so, we get one point as (5,6500)
After 7 minutes it is at a height of 5900 feet
so, we get another point as (7,5900)
we can use point slope form of line

points as
(5,6500)
x1=5, y1=6500
(7,5900)
x2=7 , y2=5900
Calculation of slope(m):

now, we can plug values


Equation of line:
we can use formula

we can plug values


Time of landing:
we can set h=0
and then we can solve for t

..............Answer
Answer:
B) false D) true E) true
Step-by-step explanation:
Plug in numbers to disprove the first one.
Area formula for triangles says D is true
It's the Pythagorean's Theorem for Heaven's sakes.
