When you write a function in the form 
, y is the dependent variable, and x is the independent variable.
So, if b is the independent variable, it means that we have to solve the expression for r.
To do so, we perform the following steps: start with
Add 12 to both sides
Divide both sides by 4:
So, we wrote the expression in the form 
, which means that r is the dependent variable and b is the independent variable, as requested.
Answer:
x>-2
Step-by-step explanation:
-9x-15<3
+15<+15 add 15 to both sides
_________
-9x<18
÷-9 <÷-9 divide both sides by -9, switch inequality _________ symbol when dividing by negative number.
x>-2 Answer
_________
In step 3, you added 8x onto the other side instead of subtracting it from 15x.
yes i agree because if all the integers are positive, the answer stays positive which means if you know your integer rules: a positive divide by a positive it stays positive. its the same thing for all the other operations. hope this helps.
Answer:
The height of the pyramid is 
Step-by-step explanation:
we know that
The volume of the pyramid is equal to
where B is the area of the base of the pyramid
h is the height of the pyramid
we have
----> the area of the base is the area of a rectangle
substitute the values in the formula and solve for h
