Answer:
A. -1 ≤ x ≤ 3
Step-by-step explanation:
The range is the horizontal extent of the graph--the set of x-values for which the function is defined. Here, the graph extends from x = -1 to x = 3, with both end points included. The range is ...
-1 ≤ x ≤ 3
Answer:
DE=5*8=40
Step-by-step explanation:
DE+EF=DF
5x+17x-20=20x-4
22x-20=20x-4
22x-20x=-4+20
2x=16
x=16/2
x=8
DE=5x
DE=5*8=40
If a^2+b^2=c^2 then it's a right triangle
If c^2>a^2+b^2 then it's obtuse
If c^2< a^2+b^2 then it's acute
It is 54,000 feet. Area is length times width (300 times 180).
