Two trains leave stations 308 miles apart at the same time and travel toward each other. One train travels at 60 miles per hour while the other travels at 80
miles per hour. How long will it take for the two trains to meet?
Do not do any rounding.
answer: about 22.67
step-by-step explanation:
find the vertical and horizontal asymptotes of the function f x = 5 x − 1 . to find the vertical asymptote, equate the denominator to zero and solve for . since the degree of the polynomial in the numerator is less than that of the denominator, the horizontal asymptote is .

1) n+n+1+n+2=51
3n+3=51
3n=48
n=16
the three numbers are 16, 17 and 18.
2) x+15=4x
3x=15
x=5

3) the two digits are x and y.
y=3x
(10x+y)+(10y+x)=88
y=3x
11x+11y=88
y=3x
x+y=8
x+3x=8
x=2
the original number can be either 28 or 82.
4) n+(n+2)+(n+4)=48
3n+6=48
3n=42
n=14
the numbers are 14, 16 and 18.
5) y=x+3
10y+x+10x+y=143
y=x+3
11x+11y=143
y=x+3
x+y=13
x+x+3=13
2x=10
x=5
the original number can be 57 or 75.
hope this !
slope = (y2 -y1) ÷ (x2 -x1)
slope = (0 -0) / (-5, -7)
slope = 0 / -12 = 0
the slope of the line is zero. it is perfectly horizontal.
