Answer:
The function is increasing when the slope is greater than zero and decreasing when the slope is less than zero. Slope is (y2-y1)/(x2-x1) or the change in y divided by the change in x.
In this case the function is decreasing when x=[-8,-5) and when x=[4,8)
So in interval notation: x=[-8,-5)U[4,8)

First find the slope of the given line. 6x+4y=3. Isolate y. 4y=-6x+3, y=-3/2x+3/4.
The slope is -3/2. A perpendicular slope would equal the negative reciprocal of -3/2, which is 2/3.
The answer would be any line with a slope of 2/3 (ie y=2/3x-1).
To check, graph the given and derived equation.
It would take Maren 80 minutes, or 1 hr and 20 min. Just divide the 24 minutes by the 3 in the numerator, then find out how many 1/5's it takes to get 2 and multiply that by what you got as your quotient

Step-by-step explanation:
1) Apply distributive property:
Subtract 10 from both sides of the equation and then divide both sides by 2:
2) Apply distributive property:
Add 3 to both sides of the equation and then divide both sides by -3:
3) Apply distributive property:
Add 4 to both sides of the equation:
Multiply both sides by :
4) Apply distributive property:
Add to both sides of the equation:
Multiply both sides by :
