Answer:
C) If the leading coefficient of g(x) is 1, all rational roots of g(x) = 0 must be integers.

Answer:
B
Step-by-step explanation:
$40 is the flat fee of hooking a vehicle. It does not depend on m, miles towed.
$1.70 depends on miles towed, m. So if m miles are towed, the towing fee would be 1.70 * m, or 1.70m.
THAT, would be added to the initial fixed me of $40.
Hence, total charges, c, would be 40 + 1.70m
Answer choice B is right.
Answer:
5 apples
Step-by-step explanation:
20 - 15 = 5
Let's call 'it' x. 1/2 is equal to one third of x, so we could say that 1/3x = 1/2
Now we just have a simple equation to solve:
1/3x = 1/2
x = (1/2) / (1/3)
Dividing by a rational number (such as 1/3, which is expressed in fraction form) is the same as multiplying by its reciprocal (the reciprocal of a fraction is itself when the numerator and denominator have been swapped). Therefore
x = (1/2) / (1/3) = (1/2) * 3 = 3/2 = 1.5
To check this answer, test the statement. Half is a third of x, where x=1.5:
1.5 / 3 = 0.5 = 1/2
