Answer:
ΔABC ≈ ΔDEF
∡B ≅ ∡E
x = 4.5
BC is similar to EF
Step-by-step explanation:
to find 'x':
6/16 = x/12
16x = 72
x = 4.5
Answer: increasing = [-4, ∞)
decreasing = Never
positive = Never
negative = [-4, ∞)
<u>Step-by-step explanation:</u>
The curve is increasing starting at x = -4 and appears to have an asymptote at y = 0 so never crosses the x-axis.
It never decreases and never goes past y = 0 so is never positive.
The return trip took 1 hour 42 minutes longer
Further explanation:
The distance will remain same on return.
The formula for speed is given by:

Let d be the distance
s1 be the speed while going and s2 be the speed while returning
and
t1 be the time while going and t2 be the time while returning
d=500 miles
s1=60 miles per hour
s2=50 miles per hour
We have to calculate time for both trips,
So,
<u>Time while Going:</u>
<u>
</u>
<u>Putting the values of d and s1</u>
<u>
</u>
<u>Converting 8.3</u>
8 will be the hours,
for 0.3 hour
0.3*60=18 minutes
The first trip took 8 hours and 18 minutes.
<u>Time while returning:</u>

Putting the values of d and s1

The difference of both times is: 1 hour 42 minutes
So,
The return trip took 1 hour 42 minutes longer

Answer:
The graph of the circle
Step-by-step explanation:
A function is defined to have only one output per input. Conducting the horizontal line test, we see that there are instances where the line intersects two points, which shows that some inputs have multiple outputs.
This does not fit the definition of a function.
I hope this helps! :)
