Complete question :
The Daily Info charges a fee $650 of plus $80 per week to run an ad. The People's Paper charges $145 per week. Write an inequality to represent the number of weeks an ad must run for the total cost at the Daily Info to be less expensive than the cost at the People's Paper. Let w be the number of weeks the ad runs in the paper
Answer:
650 + 80w < 145w
Step-by-step explanation:
Given that :
Number of weeks ad will run = w
Daily Info total cost :
650 + 80w
The People's Paper total cost:
145w
Number of weeks ad should run For cost at daily info to be less expensive than peoples choice';
Daily Info total cost < people's choice
650 + 80w < 145w
650 < 145w - 80w
650 < 65w
650/65 < 65w / 65
10 < w
w > 10
I assume your "reasons" mean "roots" or "zeros"
if 3 is a root, plug x=3 in the equation, you can find n:
3²+(n-1)*3+6=0
3(n-1)=-15
n-1=-5
n=-4
Plug n=-4 in the original equation: x²-5x+6=0
factor: (x-3)(x-2)=0
x=3, which we already know
or x=2, which is the value of m+4
m+4=2
m=-2
