Step-by-step explanation:
Step 1
find the coordinates of the factory
the <span>factory is 104 miles due north of the warehouse
the coordinates of the warehouse are (39,-52)
coordinates of the factory------> (39,-52+104)------> (39,52)
step 2
find the distance warehouse to airport
let
A coordinates of warehouse-------> A( 39,-52)
B coordinates of airport---------> B(-39,52)
C coordinates of factory-------> C(39,52)
distance AB=</span>√[(52+52)²+(-39-39)²]------> distance AB=130 miles
<span>
step 3
find the distance airport to factory
B(-39,52)
</span>C(39,52)
distance BC=√[(52-52)²+(39+39)²]-----> distance BC=39 miles
<span>the total number of miles=distance AB+distance BC---> 130+39
</span><span>the total number of miles=169 miles
</span>
the answer is
169 miles
(3/20) x 3 (4/15) x4
9/60 + 12/60
= 21/60
=7/20
ANSWER
A. -4
EXPLANATION
The slope of parallel lines are equal.
Since the green line is parallel to the red line,then they have the same slope .
Since the green line has a slope of -4, the red line also has a slope of -4.
The correct choice is A
