Answer:
the slope is -2/5
Step-by-step explanation:
it did the question and got it right
Remark
The formula for a discriminate is b² - 4*a*c
a = 2
b = 1
c = - 3
So the discriminate =
D = (1)² - 4*2*(-3)
D = 1 - - 24
D = 25
Answer:
14
Step-by-step explanation:
you have to add 3 to the first of the two numbers. for example 5+3=8 so the answer would be 58, and because you're decreasing each number by 10 you would have to add 1+3=4 so tha answer must be 14.
M represents miles
35+0.10m=25+0.15m
35-25+0.10m=25-25+0.15m
10+0.10m=0.15m
10+0.10m-0.10m=0.15m-0.10m
10=0.05m
m=200
Check:
35+0.10(200)=25+0.15(200)
35+20=25+30
55=55
The solution: m=200 is true.
After 200 miles driven, prices charged by both companies will be the same.
