20=3x-5-2x
20+5=3x-2x
25=x
Answer:
y=2x-5
Step-by-step explanation:
y=mx+b
m=slope
b=y-intercept
m=2
b=-5
we know that
the equation
describe a vertical parabola with vertex at point 
if 
-------> the parabola open Up and the vertex is a minimum
if 
-------> the parabola open Down and the vertex is a maximum
in this problem we have
---> because is positive (given problem)
so
The vertex is a minimum
therefore
<u>the answer is the option C</u>
Up
