Answer:
The slope is -2
Step-by-step explanation:
Since the roof is decreasing in height as it goes forward, I know that the slope must be negative. The equation to find the slope is rise/run. The vertical change, or the rise, is -6 feet, so that value goes on top of the fraction. The horizontal value, or the run, is 3 feet so that goes on the bottom of the fraction.
Now our fraction is 
If you simplify that fraction, you'll get -2.
Answer:
9
Step-by-step explanation:

Therefore x(x+1)≤0, and if two numbers multiply to a negative number, one of them has to be negative and the other has to be positive. In this case, because x+1>x, x≤0, and x+1≥0
Therefore -1≤x≤0, and x can take up the value of any real number in the interval [-1,0]
Answer: y = 980.333
Step-by-step explanation:
y-18=14
add 18 to each side
y = 32
Substitute 32 for y in 3(y+5)
3(32 + 5)
3(37)
111
So 3(y+5) = 111
Find the value of the variable y:
y-18=14 Add 18 on both sides:
y = 32
= 3y+15
_____________________
3y+15 = 2,956
3y+15 = 2956
3y = 2941
y = 980.333
