A roof drops 6 feet for every 3 feet forword,determine the slope of the roof the slope can be positive or negative
dalvyx [7]

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 \frac{-6}{3}

If you simplify that fraction, you'll get -2.

1/x - 1/(x+1) ≤ 0 Please help quickly
Ymorist [56]
\frac{1}{x}- \frac{1}{x+1}= \frac{(x+1)-x}{x(x+1)}= \frac{1}{x(x+1)} \leq 0

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]

If y - 18 = 14, then what is the value of 3(y + 5) ?
shtirl [24]

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
