2(3b+6) =78
Expanding the left side of the equation:
6b + 12 = 78
Solving for b:
6b = 66
b = 11
Now we will check the left side and the right side of the equation:
2(3(11) + 6) = 2(33+6) = 2(39) = 78
On the other side of the equation:
-2(6c-3) = -72
Expanding the left side of the equation:
-12c + 6 = -72
Solving for c:
-12c = -78
c = 6.5
Now we will check the left side and the right side of the equation:
-2(6(6.5) - 3) = -2(39 -3) = -2(36) = -72
This equation is true, the left side of the equation equals to the right side of the equation.
The solution for the first equation is b = 11
The solution for the second equation is c = 6.5

What is the value of f of 2?.
The value of f of 2, which means f(2), is 6.
As we know,
f'(x) = [tex]\[ \lim_{h\to0}[/tex] [f(x+h) - f(x)]/h
= [tex]\[ \lim_{h\to0}\\[/tex] [f(3x + 3h)/3 - f(3x + 0)/3]/h
= [tex]\[ \lim_{h\to0}\\[/tex] [{2 + f(3x) + f(3h)}/3 - {2 + f(3x) + f(0)}/3]/h
∴f'(x) = [tex]\[ \lim_{h\to0}\\[/tex] [f(3h) - f(0)]/3h-0 = f'(0)
⇒ f′(2) = f′(0) = 2 [∵f′(2) = 2]
⇒f′(x) = 2
Now, apply integration on the above equation with respect to x
∴f(x) = 2x + c (1)
Substituting x = 0 = y in f{(x+y)/3} = {2 + f(x) + f(y)]/3
⇒3f(0) = 2 + f(0) + f(0)
∴f(0) = 2
By equation (i) f(0) = 2.0 + c
∴c = 2 [∵f(0) = 2]
Now (1) becomes
∴f(x) = 2(x + 1)

b. A large box of fruit costs $7 and a small box of fruit costs $3. What is the juz band's profit?
Jazz Band Makes $785 in Profit.
What is the juz band's profit ?31 huge boxes and 74 little boxes of fruit are sold by the jazz band.
The cost is $x and the price is $20 for each huge fruit box.
Price minus Cost is referred to as profit.
Profit therefore equals 20 - x for one large fruit box.
31 huge fruit boxes at a profit (20 - x)
Each little fruit box costs $10 and costs $10 per small fruit box.
Each tiny fruit box has a profit of 10–y.
74 little fruit boxes worth of profit (10 - y)
For 74 small boxes and 31 large boxes, the overall profit will be:
Profit overall equals 31 (20-x) + 74. (10 - y)
We can reduce the problem above by using the distributive property as follows:
Total profit is equal to 31(20)-31x + 74(10)-74y.
Profit total = 1360 - 31 x - 74 y
Part B)
Each large package is estimated to cost $9.
Accordingly, x = 9.
Each tiny box is stated to cost $4.
Therefore, y = 4.
We can determine the Jazz Band's profit by using the x and y numbers from the profit equation.

Rachel's non-brokerage fee-related closing costs can be calculated by subtracting the brokerage fee from her total closing costs.
Since the brokerage fee was 6%, the fee comes out to be $1,105.20. To calculate the non-brokerage-related closing costs, subtract $1,105.20 from the total closing costs of $18,427, which yields a total of $17,321.80.
18427-1105.20=17321.80
This is the amount of non-brokerage fee-related closing costs that Rachel paid for her home. Rachel's net gain from the sale of her home was $230,063, which is the difference between the sale price of her home and the total closing costs, including the brokerage fee.

The domain of a function is not always all real numbers.
We know that the domain of function is the set of all possible input values for which the function is well defined.
And the range of function is the set of all possible output values for given input.
As we know the domain of a function, f(x), is all real numbers when there are no restrictions on what we can take input for x, as all real numbers would make function f(x) true.
But the domain of a function is not always all real numbers.
consider the function f(x) = 1/x
This function is not defined for x = 0
So, the domain of above function f(x) is R - {0}
