Answer:
y=40-15x
Step-by-step explanation:
Let x represent the number of hours.
We have been given that Dudley travels 30 miles every 2 hours, so distance covered in each hour by Dudley would be:
.
Since Dudley travels 15 km per hour, so distance covered in x hours would be 15x.
We have been given that Dudley wants to cover 40 miles. So we can represent our given information in an equation as:
, where, y represents number of miles he has left to travel, after biking x hours.
Answer:
$3,799.20
Step-by-step explanation:
We presume your formula is intended to be ...
M = Pm(1 + m)^(na)/((1 + m)^(na) - 1)
where M is the monthly payment, m is the monthly interest rate, n is 12, and a is the number of years.
This formula gives written below:
M = 3500·(.08/12)·(1 + (.08/12))^(12·2)/((1 + (.08/12))^(12·2) -1) ≈ 158.30
The total payback will be the sum of 24 of these payments is written below;
payback = 24×$158.30 = $3,799.20
X^2 + 6x +9
(x+3) (x+3)
x+3 = 0
x = -3
answer: x=-3
