x^2+7x+12 can be done by factoring as a process of ax^2+bx+c, whereas a is equal to 1.
First, we need to know 2 numbers that multiply to 12 and add to 7. In that case, that would be 6 and 2. And then finally write the variable x in the first parts of the parentheses, that would be: (x+6)(x+2).
Answer:
h=12 in
Step-by-step explanation:
volume of cube=1/3πr²h
113.04=1/3×3.14×3²×h
h=113.04/(3.14×3)=37.68/3.14=12 in.
Answer:
If the slope is positive it is increasing if the slope is negative it is decreasing :)
Example:
Y=mX+b
If m is positive it is a positive slope
You have to multiply, so you get 7 1/2
Okay so first plug this in
8-5
——
5-6
3/-1
-3
Slope= -3
y=-3x+b
Next, plug in one of the points to find b.
5=-3(6)+b
5=-18+b
+18 +18
—————
23=b
y=-3x+23
Hope this helps!!
