Ответ:
Given that, Don's Car Rentals charges a flat rate of $35 per day plus $2 per mile.
The number of miles is represented by m.
For 1 mile the charge is $2. So, for m miles the charges will be 2m.
Since, Don's Car Rentals charges a flat rate of $35 per day .
So, total charge must be the sum of 35 and 2m.
Hence, the algebraic expression representing the overall rate for the day is
35 + 2m.
Hope this helps you.
Ответ:
y = 0
(x+4)(x-2)=0
x+4=0 or x-2 = 0
x = -4 or x = 2
And the vertex will be (-1,-9)
The correct option is (B)
