Answer:
y=3x-2
Step-by-step explanation:
The formula for slope is y=mx=b
You can find the slope by finding two points that lie on the line (1,1) & (0,-2)
The formula for slope is 
You plug the values in and you get 
Simplify and you get 3
The slope is 3
The y-intercept (b) is -2
4,003,052 is the answer to the problem
answer x = 225 and y = -135
Step-by-step explanation:
x+y = 90 and x= 90-y and x -y = 360 so 90-y -y = 360
Suppose that this person drives at r mph going to the mountains, and gets there in 12 hours. Returning, this person drives at (r+20) mph and gets home in 8 hours. We don't know the distance yet, but can solve for the initial speed, r, by setting
d = 12r = (r+20)(8). Solving for r, r=40 mph (going) and (40+20)mph = 60 mph (returning. Since d=12 r, d = (12 hrs)(40 mph) = 480 miles (answer).
let's firstly convert the mixed fraction to improper fraction and then divide.
