Step-by-step explanation:
Answer:
The value of Discriminant of the function is -92
It has ZERO distinct real number zeros.
Step-by-step explanation:
Given:

Which is a Quadratic Equation in the general form of

where a,b and c are constants.So on comparing the given equation with general form we get,

Formula for discriminant we have

now for zeros we have

on substituting these values we get

or

the term
is imaginary
hence the zeros are not real number
Answer:

Answer:
0.5x+20=0.25x+30, m=40
Step-by-step explanation:
Blue: y=0.5x+20
Red: y=0.25+30
We’re looking for where the y (cost) is equal, so we can set the two equations to each other:
Isolate x:
0.5x+20=0.25x+30
0.5x+20-20=0.25x+30-20
0.5x=0.25x+10
0.5x-0.25x=0.25x+10-0.25x
0.25x=10
x=40
m= 40
