A) The solution is the point where the lines intersect: (5, 2.5)
b) The horizontal line has equation
.. y = 2.5
The downward-sloping line can be written in intercept form as
.. x/10 +y/5 = 1
or in standard form as
.. x +2y = 10 . . . . . . . . . (multiply the above equation by 10)
Answer:
93.6 feet
Step-by-step explanation:
------------------------------------------------------------------------
Find the value of y
------------------------------------------------------------------------
y - 18 = 14
+ 18 + 18
y = 32
------------------------------------------------------------------------
substitute y = 32 into 2 (y + 9)
------------------------------------------------------------------------
2( y + 9 ) = 2 ( 32 + 9 )
2 (y + 9 ) = 2 (41)
2 ( y + 9 ) = 82
------------------------------------
Answer: 82
