Solve as a simultaneous equation maybe?
f(x) + g(x) = 2x or x/(x-6) + y =2x
and then solve so it becomes 2x^2 + 5x =y
then factorise into brackets or use quadratic formula
Answer:
Step-by-step explanation:
First you must find the number of cubic feet in the pool. (That's volume)
Formula
V = l*w*h
Givens
Solution
<em><u>Volume</u></em>
V = 38 * 22 * 8
V = 6688 cubic feet.
<em><u>Gallons</u></em>
1 cubic foot = 7.5 gallons
6688 ft^3 = x
<em><u>Proportion</u></em>
1/6688 = 7.5 / x Cross Multiply
x * 1 = 7.5 * 6688
x = 50160 gallons
Answer:
20 pine trees
Step-by-step explanation:
No of pine trees today = 63
No of pine trees there = 43
So no of pine trees planted today= 63-43= 20
We can not really tell in this question as you dont know the equation that is being used for the domain and range relationship but overall one should know that:
The set of values of the independent variable(s) for which a function or relation is defined as the domain of a function. Typically, this is the set of x-values that give rise to real y-values.
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.
