Answer:
Step-by-step explanation:
Given: 
Since the equation is written in slope-intercept form, it is extremely easy to find the y-intercept. Slope-intercept form is written as:
Whereas:
y: range
m: slope
x: domain
b: y-intercept
With that in mind, we can immediately tell that 6 is the y-intercept.
5-x=12
Subtract 5 on both sides -1x=7 than divide 7 by -1 and you get x=-7
Answer:
48 km.
Step-by-step explanation:
Multiply 6 and 8, you get 48.
(x+3)(x+3) = x^2 -3 + 3x
x^2 + 3x + 3x + 9 = x^2 + 3x - 3
x^2 + 6x + 9 = x^2 + 3x - 3
6x + 9 = 3x - 3
3x + 9 = -3
3x = -12
x = -4
Check:
(-4+3)^2 = (-4)^2 - 3(1+4)
(-1)^2 = 16 - 3(5)
1 = 16-15
1 = 1 :)
The answer is 246.7799352750809, but you can round it and say 246.78
