Answer: Yes, she can drive round-trip to see her cousin on the free gas.
Step-by-step explanation:
Given : Ms o'Malley cousin live 1,650 miles away.
Ms o'Malley won a gift card for 100 gallons of gas.
I her car can travel 35 miles on each gallon.
Then, the total distance she can cover in 100 gallons of gas =
Since 3500 miles > 1,650 miles
It means she can drive round-trip to see her cousin on the free gas.
hence, the correct answer is "Yes".

Answer:
C
Step-by-step explanation:
ley y = f(x) and rearrange making x the subject
y = - 1 ( add 1 to both sides )
y + 1 = ( multiply both sides by (x + 5)
(y + 1)(x + 5) = 1 ← expand factors using FOIL
xy + 5y + x + 5 = 1 , that is
xy + x + 5y + 5 = 1 ( factor first/second and third/fourth terms on left side )
x(y + 1) + 5(y + 1) = 1 ← factor out (y + 1) from each term on left side
(y + 1)(x + 5) = 1 ( divide both sides by (y + 1) )
x + 5 = ( subtract 5 from both sides )
x = - 5
Change y back into terms of x with x = (x) , then
(x) =
- 5 where x ≠ - 1
