You do
$4000 x .03 x 4
= 480
Now you do
4000 + 480
= 4480
=$4,480
If you let X = the distance in miles from Dales's house, and understand rate = distance/ time, the rate going to mountains = x/7, and back from mountains is x/5. If dale was 18mph fast going home, the equation would be...
(coming home rate) = (going to mountain rate) + 18 which is
x/5 = x/7 + 18. Then solve for X.
Use the least common denominator = 35 so multiply everything by 35 and you get...
7x = 5x+630
simplify...
2x = 630, then
x = 315 .
Dale live 315 miles away from the mountains.
So the point-slope form looks like (y-y1) = m(x-x1)
So the first thing we should do is solve for m. We can do this using the slope formula (y1-y2)/(x1 - x2)
(-4 - 4)/(3 - -1) = -2
So our slope is -2. Then plug in any order pair for y1 and x2
So a possible solution is y - 4 = -2(x + 1)
Hopes this helps!
